H7144-1 from Shanghai Siproin Microelectronics, in a SOT-23. 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 / common return for the regulator. Tied to the negative rail of both the input and output decoupling capacitors at a single-point ground. |
| 2 | VOUT | power_out | Regulated 4.4V output (min 4.312V, max 4.488V at IOUT=10mA). Sources up to 50mA (typ 30mA). Requires a 10µF output capacitor (CL) to the single-point GND for stability. |
| 3 | VIN | power_in | Unregulated input supply, 5.4V to 15V for normal operation (18V absolute max, -0.3V min). Requires a 10µF input capacitor (Cin) to GND. Dropout is ~20mV typical at IOUT=1mA. |
