LP2985AIM5X-3.0

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

LP2985AIM5X-3.0 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply pin; use a capacitor of 1µF or larger from this pin to ground.
2 GND power_in Ground pin of the regulator.
3 ON/OFF input Enable pin: driving it high enables the device and driving it low disables it; tie it to VIN if unused.
4 BYPASS bidirectional Bypass pin for low-noise performance; an external capacitor between BYPASS and ground reduces reference voltage noise.
5 VOUT output Regulator output; use a capacitor of 2.2µF or larger from this pin to ground, with nominal capacitance greater than 2.2µF and effective capacitance at the pin greater than 1µF.
