LP2985A-33DBVT

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

LP2985A-33DBVT 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 (2.5V to 16V); decoupling with ≥1µF capacitor to ground required.
2 GND power_in Ground (negative supply reference).
3 ON/OFF input Logic input enable control; drive high to enable, low to disable; tie to VIN if unused.
4 BYPASS bidirectional Bypass capacitor connection to reduce reference voltage noise.
5 VOUT power_out Regulated output supply (1.2V to 5.0V); requires ≥2.2µF output capacitor; maximum 150mA output current.
