# ST715MR

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

ST715MR from STMicroelectronics, 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 | FB | input | Feedback input for output voltage adjustment via external voltage divider; reference voltage 1.2 V typical (1.152-1.248 V measured over -40-125 °C). |
| 2 | GND | power_in | Ground connection. |
| 3 | NC | unconnected | Not internally connected. |
| 4 | IN | power_in | Power supply input; operates from 2.5 V to 24 V with 85 mA guaranteed output and 500 mV typical dropout voltage. |
| 5 | OUT | power_out | Regulated output voltage; adjustable from 1.2 V to 5.0 V in 100 mV steps via external voltage divider connected to feedback pin. |
