PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223
PJ1117ST-5.0 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/ADJ | power_in | Ground reference on the fixed-voltage versions, and the adjust/feedback pin on the ADJ version, where the 1.25V reference and about 55µA typical adjust current (120µA maximum) set the output through R1 and R2. |
| 2 | VOUT | power_out | Regulated output that supplies up to 1.0A maximum output current, with a dropout of 1.5V maximum at 1A. |
| 3 | VIN | power_in | Power input with a recommended maximum of 15V, and an absolute supply voltage rating of 18V. |
