LD2980ABM30TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

LD2980ABM30TR from STMicroelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Positive supply input; operating voltage range 2.5 to 16 V provides power for the regulator.
2 GND power_in Ground reference pin; return path for all currents.
3 INHIBIT input Logic-controlled ON/OFF shutdown input; output disabled when INHIBIT < 0.18 V, enabled when INHIBIT > 1.3 V; not internally pulled and must not be left floating.
4 NC unconnected No connection.
5 VOUT output Regulated 3.0 V output; nominal 3.0 V at 1 mA load, range 2.978 to 3.023 V for 1 to 50 mA load at 25°C.
