MIC29302WS

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-5

MIC29302WS from HGSEMI, in a TO-263-5. 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 EN input TTL/CMOS logic enable input that shuts down the regulator when low (below 0.8V) and turns it on when high (above 2.4V); connect to IN for continuous operation.
2 IN power_in Regulator supply input with operating range 3V to 16V (absolute maximum 26V), protected against reversed input polarity.
3 GND power_in Ground pin; the metal tab is also connected to GND.
4 OUT power_out Regulated output delivering up to 3A, requiring an output capacitor (stable with 10 µF at full load).
5 ADJ input Adjust input that sets the output voltage between 1.24V and 15V via an external two-resistor divider, with a reference of 1.215V to 1.267V.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
