LP2985AIM5-3.3

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

LP2985AIM5-3.3 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply pin, operating voltage range 2.5V to 16V; use ≥1µF capacitor from this pin to ground.
2 GND power_in Ground reference connection.
3 ON/OFF input Enable pin for the LDO; output is enabled when voltage exceeds high threshold and disabled when below low threshold; tie to VIN if enable function is not used.
4 BYPASS bidirectional Reference bypass pin for low-noise performance; connect external capacitor between this pin and ground to reduce reference voltage noise to 30µVRMS.
5 VOUT power_out Regulated output voltage (3.3V nominal); use ≥2.2µF ceramic capacitor from this pin to ground.
