LP2985IM5X-4.5

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

LP2985IM5X-4.5 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 with a value 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 to VIN if unused.
4 BYPASS bidirectional Connecting an external capacitor between the BYPASS pin and ground reduces reference voltage noise.
5 VOUT power_out Regulator output; use a capacitor with a value of 2.2µF or larger from this pin to ground, with nominal output capacitance greater than 2.2µF.
