8682l Datasheet [new] ◎

There is no universal standard for part numbers. Always compare the physical package and circuit context before assuming compatibility. Part 2: Key Electrical Specifications (Typical Values) While an official datasheet from a specific manufacturer is definitive, the following table represents the most commonly cited specifications for devices matching the 8682l designation in repair and design communities.

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. Part 4: Typical Application Circuit The 8682l is simplicity itself. A basic fixed voltage regulator circuit requires only two external capacitors:

| SMD Marking Code | Likely Output Voltage | Package | | :--- | :--- | :--- | | | 3.3V | SOT-23 | | 682L | 5.0V | SOT-23 | | 8L2 | 8.0V | SOT-89 | 8682l Datasheet

| Substitute Part | Key Difference | When to Use It | | :--- | :--- | :--- | | | Higher max current (800mA), larger package (SOT-223) | When needing >300mA. Not pin-compatible with SOT-23. | | XC6206P332MR | Ultra-low quiescent current (1µA), same pinout (SOT-23) | For battery-powered upgrades. Direct substitute for 3.3V variant. | | 78L05 | Standard dropout (1.7V), TO-92 package only | For older through-hole designs, but dropout is much worse. | | MCP1700-3302E | Very low quiescent (1.6µA), SOT-23 | Modern replacement for 3.3V 8682l in low-power IoT. | Warning: Never replace a fixed-output 8682l with an adjustable regulator (like LM317) without external resistor networks. That will change the circuit behavior. Part 8: Troubleshooting Common Failures When a circuit containing an 8682l fails, here’s a diagnostic flowchart:

A: That is a different device. A 6-pin 8682l is likely a dual LDO or a MOSFET driver. Search for "SOT-23-6 8682l marking." Do not use the 3-pin datasheet. There is no universal standard for part numbers

This article compiles everything you need to know about the 8682l. Whether you are troubleshooting a power supply, designing a consumer electronics product, or cross-referencing a part for a repair, this guide will decode the technical specifications, pin configuration, electrical characteristics, and practical applications of the 8682l.
