ST715M33R

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

ST715M33R from STMicroelectronics, 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 NC unconnected Not internally connected pin; may be left floating or connected to ground.
2 GND power_in Common ground reference for the regulator; serves as return path for input bypass capacitor and output capacitor connections.
3 NC unconnected Not internally connected pin; may be left floating or connected to ground.
4 IN power_in Input voltage supply accepting 2.5 V to 24 V operating range (-0.3 to 26 V absolute maximum) with 0.1 µF minimum bypass capacitor recommended between IN and GND.
5 OUT power_out Regulated 3.3 V output voltage with ±5% total accuracy at 0 to 85 mA continuous output current; requires 0.47 µF minimum output capacitor between OUT and GND.
