LP2980AIM5-ADJ

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

LP2980AIM5-ADJ from HGSEMI, in a SOT-23-5. 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 VIN power_in Input supply pin with a 2.5V to 16V operating range, and a 1μF or larger input capacitor must be placed within 0.5 inch of it.
2 GND power_in Common ground pin (device substrate) that serves as the clean analog ground return for the input and output capacitors.
3 ON/OFF input Logic high enable pin that must be actively driven or tied to VIN when unused, with turn-on and turn-off signals slewing faster than 40mV/μs.
4 ADJ input Output voltage feedback pin that connects to ground through a recommended 51.1kΩ resistor, with an ADJ pin bias current of 150nA typical and 350nA maximum.
5 VOUT power_out Regulated output pin, adjustable from 1.23V to 15V and specified for 50mA output current, which requires an external Schottky diode from VIN to VOUT if the output may be pulled above the input.
