LM1117MPX-50NOPB

onsemi · Linear Voltage Regulators (LDO) · SOT-223

LM1117MPX-50NOPB from onsemi, 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 Adjust/Ground power_in Pin 1 is the Adjust/Ground terminal, which serves as the ground reference for the 5.0 V fixed-output device; the adjust pin current Iadj is typically 52 µA with a maximum of 120 µA.
2 Output power_out Pin 2 is the regulated output and is electrically connected to the heatsink tab; output current limit is 1000 mA minimum, 1500 mA typical, and 2200 mA maximum, with infinite output short-circuit duration.
3 Input power_in Pin 3 is the unregulated input with a maximum input voltage of 20 V, and for the 5.0 V device the input must be at least 6.5 V to 12 V to hold regulation over 0 to 800 mA; output current must not exceed 1.0 A when Vin is greater than 12 V.
