ST732M28R

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

ST732M28R from STMicroelectronics, in a SOT-23-5L. 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 GND power_in Ground reference pin; all voltages in the datasheet are referred to GND.
2 VIN power_in Input voltage pin with an operating range of 2.5 V to 28 V and an absolute maximum DC input of -0.3 V to 30 V.
3 VOUT power_out Regulated output voltage pin that supplies up to 300 mA and needs a minimum 0.47 µF output capacitor for stability.
4 NC unconnected Not internally connected.
5 NC unconnected Not internally connected.
