PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
PJ75BL33SC from PJSEMI, in a SOT-23-3. 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 for the regulator; input and output capacitors connect between VIN/OUT and GND, and a wide copper trace is required for both VIN and GND. |
| 2 | VOUT | power_out | Regulated output requiring a 1µF to 10µF ceramic output capacitor with ESR from 5mΩ to 100mΩ, placed as close as possible to the OUT and GND pins; output current is clamped to approximately 80mA during short-circuit. |
| 3 | VIN | power_in | Power input with a supply range of 3V to 36V (absolute maximum supply voltage -0.3V to +40V); a 1µF to 10µF ceramic input capacitor is recommended between VIN and GND. |
