RT9013-25GB from Richtek Tech, 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 | VIN | power_in | Supply input, operating range 2.2V to 5.5V with 6V absolute maximum supply input voltage. |
| 2 | GND | power_in | Common ground for the regulator; on this package it is pin 2 of the SOT-23-5 / SC-70-5 pinout. |
| 3 | EN | input | Enable input, active high: logic low (VIL 0 to 0.6V) puts the device in shutdown and logic high (VIH 1.6V to 5.5V) turns it on; it is CMOS logic and cannot be left floating, with a 6V absolute maximum. |
| 4 | NC | unconnected | No internal connection; leave unconnected. |
| 5 | VOUT | power_out | Regulator output, which requires at least a 1µF ceramic output capacitor for stability with ESR greater than 5mΩ. |
