8682l Ic Datasheet Access

These ICs are commonly found in small form-factor packages, such as the SSOP-10 or similar surface-mount footprints.

Based on reverse-engineered circuits from devices like Bluetooth headsets, small power banks, and LED drivers, the 8682L in a 5-pin SOT-23 package typically follows this pinout:

| Pin No. | Name | Description | |---------|------------|------------------------------------| | 1 | VIN | Input voltage (2.5V – 6.0V) | | 2 | GND | Ground | | 3 | EN (or NC) | Enable pin (active high, tie to VIN if unused) | | 4 | NC / ADJ | No connect or feedback/adjust | | 5 | VOUT | Regulated output voltage |

For SOT-89 package (3-pin):
1 – VIN, 2 – GND, 3 – VOUT (fixed voltage). No enable pin. 8682l ic datasheet

For SOT-23-6 variant (sometimes labeled 8682L):
Pins 1-6: VIN, GND, EN, BP (bypass), FB (feedback), VOUT.

⚠️ Warning: Without the original datasheet, these pinouts are derived from common LDO topologies. Always test continuity and voltage behavior on a known working board or use a component tester.

| Parameter | 8682L | LM317 (Classic) | |-----------|-------|-----------------| | Dropout @ 1A | 0.38V | 2.0V | | Quiescent current | 4mA | 5mA (plus divider current) | | Max output | 1.5A | 1.5A | | Min input/output differential | 0.5V | 3.0V | | Shutdown pin | Yes | No | These ICs are commonly found in small form-factor

The 8682L clearly wins in low-dropout scenarios, making it suitable for battery-powered devices where the input voltage sags close to the output.

The 8682L is most commonly housed in a 6-pin SOT-23 package. Below is the standard pin configuration derived from multiple field extractions and partial datasheets.

| Pin No. | Name | Function Description | |---------|-----------|-------------------------------------------------------------| | 1 | CHRG | Open-drain charge status output (active low – charging) | | 2 | GND | Ground connection | | 3 | BAT | Battery connection pin (to positive terminal of Li-ion cell) | | 4 | VCC | Input supply voltage (4.5V to 6.5V typical) | | 5 | STDBY | Open-drain standby/complete status output (active low – done)| | 6 | PROG | Charge current programming pin (connect resistor to GND) | | Parameter | 8682L | LM317 (Classic) |

Alternative variant (8-pin DFN): Occasionally, the 8682L appears in an 8-pin package with additional pins for thermal pad (exposed pad for heat dissipation) and dual LED drive outputs. Always verify the top marking.

Top marking codes: Look for “8682L” directly or codes like “82L”, “68L”, or “L82” – many Chinese ICs use shorthand laser marking.
