UA78M05IDCY

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

UA78M05IDCY from Texas Instruments, in a SOT-223-4. 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 INPUT input Input pin for unregulated voltage supply; use recommended 0.33µF capacitor placed as close as possible to INPUT and COMMON pins.
2 COMMON power_in Ground reference pin.
3 OUTPUT output Regulated 5V output pin; use recommended 0.1µF capacitor placed as close as possible to OUTPUT and COMMON pins.
4 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
