7536-1 from IDCHIP, in a SOT-89. 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 | GND | power_in | Ground pin, listed in the pin table as 地 (ground); the datasheet gives no separate electrical limit for it. |
| 2 | VIN | power_in | Input pin with an absolute supply range of -0.3V to +36V, and the specified dropout and regulation tests use VIN = VOUT + 2V. |
| 3 | VOUT | power_out | Regulated output pin rated for up to 100mA (typical 100mA, minimum 70mA at VIN = VOUT + 2V), and the datasheet requires an output-to-ground capacitor greater than 2.2uF. |
