PJ9500M25SQ from PJSEMI, 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 reference pin for the regulator, with the output capacitor to be placed as close as possible to the OUT and GND pins (page 10). |
| 2 | VIN | power_in | Power input with an operating range of 1.8 V to 6 V and an absolute maximum of -0.3 V to 6 V, decoupled with a 1 µF ceramic capacitor to GND (pages 6, 7 and 10). |
| 3 | VOUT | power_out | Regulated output for the PJ9500M25SQ 2.5 V option (ordering code 25), rated for a 500 mA maximum load current, with VOUT to VIN voltage limited to -0.3 V to 5 V (pages 2, 6 and 3). |
