MIC29302AWD-TR

Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-5

MIC29302AWD-TR from Microchip Tech, in a TO-252-5. 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 Active-high TTL/CMOS-compatible enable control input that must not be left floating; connecting it to IN keeps the regulator permanently on.
2 IN power_in Unregulated input supply, specified from +3V to +16V maximum.
3 GND power_in Ground pin; the TAB is also connected internally to the IC ground on this package.
4 OUT power_out Regulator output voltage, adjustable from 1.24V to 15V using two external resistors.
5 ADJ input Feedback input receiving the 1.24V reference from the external resistor divider that sets the output voltage.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
