H7533-H# from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 | Device ground reference. Connect to the system single-point ground. Common return for both input and output current. |
| 2 | VIN | power_in | Regulator input supply. Operating range 4.75V to 40V (absolute max 45V). Bypass with a 10uF ceramic capacitor to GND close to the pin. |
| 3 | VOUT | power_out | Regulated 3.3V output (±2%), 100mA typical output current. Requires a 10uF output capacitor to GND for stability. Dropout is 600mV at 100mA. |
