# PJ9500M36SE

**PJSEMI** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

PJ9500M36SE from PJSEMI, 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 | Power input voltage, specified from 1.8V to 6V, with an absolute maximum range of -0.3V to 6V relative to GND. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Chip enable, active high: VIH minimum is 1.2V and VIL maximum is 0.9V, with the pin internally pulled to GND through 1 MΩ and high impedance when not driven. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output voltage, capable of supplying up to 500 mA; VOUT to VIN voltage is limited to -0.3V to 5V. |
