STLQ015M21R 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 | IN | power_in | Input voltage pin, operating from 1.5 V to 5.5 V, with absolute maximum DC input of -0.3 V to 7 V referred to GND. |
| 2 | GND | power_in | Ground reference; all absolute maximum ratings are referred to this pin. |
| 3 | EN | input | Enable input: set VEN high to turn the device on and VEN low to turn it off (shutdown, about 1 nA typical). |
| 4 | NC | unconnected | Not connected. |
| 5 | OUT | power_out | Regulated output voltage, 2.1 V for order code STLQ015M21R, with 150 mA guaranteed output current. |
