MPQ2019GN-AEC1-Z

Monolithic Power Systems · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8-EP

MPQ2019GN-AEC1-Z from Monolithic Power Systems, in a SOIC-8-EP. 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 OUT power_out Regulated output voltage; only a low-value ceramic capacitor (≥ 0.47μF) on the output is required for stability.
2 NC unconnected No connection.
3 GND power_in Ground; connect the exposed pad and GND to the same ground plane.
4 IN power_in Input voltage; connect a 3V to 40V supply to IN.
5 EN input Regulator on/off control input; logic low shuts down the IC and logic high starts it up, and EN should be connected to IN for automatic start-up.
6 PG output Power good open-drain output; if not used, the pin can be left floating.
7 PGDL passive Programmable power-good delay time pin set by a capacitor on PGDL; if not used, the pin can be left floating.
8 FB input Feedback input for the output-adjustable version, regulated to 1.25V nominally and used to set the output voltage.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
