PJ1117ST-3.3

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

PJ1117ST-3.3 from PJSEMI, in a SOT-223. 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/FB power_in Ground reference pin for the fixed 3.3V version (labelled GND/ADJ in the pin function table); the datasheet gives no separate electrical limit for this pin.
2 VOUT power_out Regulated 3.3V output with output voltage accuracy of -2% to +2% for 0≤IOUT≤1A and VIN=VOUT+2V, with a maximum output current of 1A.
3 VIN power_in Power input with a recommended maximum of 15V (absolute supply voltage rating 18V), and a dropout voltage of 1.3V typ / 1.5V max at IOUT=1A.
