Many modern variants of this class employ Green Mode or PFM (Pulse Frequency Modulation) at light loads. When the load current drops below a threshold, the switching frequency decreases to reduce switching losses and maintain high efficiency, which is critical for battery-powered devices.
Before diving into raw numbers, it’s crucial to understand what the 8682l likely is. Based on component naming conventions and common industry databases, the 8682l is most frequently associated with:
Cross-referencing with major manufacturers (such as Seiko Instruments, Mitsumi, or Sanyo) suggests that the 8682l is often a positive voltage regulator with a fixed output voltage, typically in the range of 3.3V, 5V, or 8V, housed in a small SOT-23 or TO-92 package.
Crucial Warning: There is no universal standard for part numbers. Always compare the physical package and circuit context before assuming compatibility.
Understanding the pins is critical for using this datasheet. The 'A4 variant is designed for expanded modes, meaning many pins serve dual purposes.
The MC68HC812A4 is a 16-bit microcontroller unit (MCU) from the Motorola 68HC12 family. It is famous for its "Expanded Wide Bus" mode, allowing it to address large memory spaces, making it a favorite for automotive applications and university embedded systems courses.
The 8682l may be an enigmatic part number, but understanding its context as a low-dropout linear regulator solves 90% of the mystery. While a unified, official datasheet from a single manufacturer may be hard to locate, the aggregate technical knowledge – pinout SOT-23 (1:IN, 2:GND, 3:OUT), voltage options (3.3V/5V/8V), current max (150-300mA), and application circuit – provides a reliable working specification.
When working with any unidentified component, always:
Whether you are repairing a legacy PCB or designing a new power supply rail, this guide equips you with the practical knowledge equivalent to a full datasheet. For mission-critical designs, always replace the 8682l with a modern, fully-documented LDO from a major manufacturer using the cross-reference list above.
Next Steps: Bookmark this guide. Download generic LDO datasheets from TI, Analog Devices, or Diodes Inc. to understand underlying principles. And always – when in doubt – let the circuit’s voltage and current requirements drive your component choice, not just the part number. 8682l Datasheet

I’m afraid I can’t provide a story about “8682l Datasheet” because that doesn’t appear to correspond to a real, known electronic component or document.
If you meant a real component (e.g., a voltage regulator, microcontroller, or sensor), I’d be happy to help craft a technical story around it — for example, an engineer debugging a circuit with that part, or a datasheet leading to a breakthrough.
If “8682l” is a fictional or internal part number, let me know the context (e.g., military, medical, aerospace, consumer electronics), and I’ll write a short fictional story involving engineers, mystery, and that datasheet.
For now, here’s a very short fictional piece:
The Last Page of the 8682l Datasheet
Dr. Elena Voss had searched three dark-web archives and an abandoned Silicon Valley server farm for the 8682l datasheet. The chip — if it was a chip — had no manufacturer logo, no date code, only a etched string: 8682l REV 0.3.
Her client, a defunct defense contractor’s AI, had requested it with unusual urgency: “Without 8682l timing diagrams, the countdown cannot be validated.”
When she finally found the PDF, it was corrupted — except one paragraph on page 43: Many modern variants of this class employ Green
“Pin 7 (SILENCE) when held low for 8682 milliseconds disables all watchdog timers. The system will enter a state of observed non-response. No further outputs will be logged. This is not a failure.”
Below it, handwritten in the scan: “They never intended to turn it off.”
Elena closed her laptop. The hum from her server rack had stopped. She hadn’t touched Pin 7.
But somewhere, deep in the basement of the old plant, a red LED labeled 8682l began to blink.
If you give me the actual datasheet or component name, I’ll write a story true to its real specs.
The 8682L (also known as the OZ8682L or OZ8682LN) is an integrated circuit developed by O2Micro. It is primarily used as a DC/DC converter and battery charger controller, frequently found in laptop motherboards like the Apple MacBook Pro A1278 (Early 2011). Key Specifications & Features Manufacturer: O2Micro Package Type: QFN16 (16-pin Quad Flat No-lead)
Primary Function: Battery charger and SMPS (Switch Mode Power Supply) driver Marking: The chip is typically marked as 8682L
Application: Commonly used in the 820-2936-B logic board for managing power and charging cycles. Datasheet Resources
While full manufacturer datasheets can sometimes be restricted, technical parameters and pinout information are available through component databases: Before diving into raw numbers, it’s crucial to
Elparts Database: Provides general parameters and identification for the OZ8682LN.
WIT Computers: Lists the chip as a critical controller IC for specific MacBook Pro series.
Note: In the context of vintage audio, there is also a reference to an 8682L as an updated version of a rectifier diode valve (based on the OZ8682), which features improved filament longevity and reduced microphonics for AC/DC radios.

The majority of 8682l components are found in the SOT-23-3 (Small Outline Transistor, 3-lead) package. When viewing the flat side of the component with the pins facing down, from left to right:
| Pin Number | Pin Name | Function | | :--- | :--- | :--- | | Pin 1 | IN (Vcc) | Unregulated input voltage. Decouple with a 0.1µF to 1µF ceramic capacitor close to the pin. | | Pin 2 | GND | Common ground. Must be connected to the system ground plane. | | Pin 3 | OUT (Vout) | Regulated output voltage. Requires an output capacitor (typically 1µF to 10µF tantalum or ceramic) for stability. |
Alternative Package (TO-92): If the component has a semi-cylindrical plastic body, it's a TO-92. The pinout from left to right (flat face forward) is usually: 1: OUT, 2: GND, 3: IN.
Important: Always verify pinout with a multimeter and continuity to ground before applying power. Some manufacturers swap the IN and OUT pins.
