# ST732M36R

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

ST732M36R from STMicroelectronics, in a SOT-23-5L. 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 | GND | power_in | Ground reference. All device voltages are referred to GND. |
| 2 | VIN | power_in | Unregulated input voltage supply. Operating range 2.5 V to 28 V (absolute max -0.3 V to 30 V). Requires a low-ESR ceramic input capacitor of at least 0.1 µF placed close to the pin. |
| 3 | VOUT | power_out | Regulated output voltage. Fixed 3.6 V for the ST732M36R variant, delivering up to 300 mA with ±2% accuracy. Requires a low-ESR ceramic output capacitor of at least 0.47 µF (ESR 5-500 mΩ) for control-loop stability. |
| 4 | NC | unconnected | Not internally connected. Leave floating or tie to a static net; no internal bond. |
| 5 | NC | unconnected | Not internally connected. Leave floating or tie to a static net; no internal bond. |
