MIC29151-5.0WU-TR

Microchip Tech · Pre-ordered MCUs · TO-263-5

MIC29151-5.0WU-TR from Microchip Tech, 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 CMOS compatible control input; logic-high = enable, logic-low = shutdown (may be tied to VIN if not needed, and to ≤30V).
2 IN power_in Supplies the current to the output power device.
3 GND power_in Ground pin; the TAB is also connected internally to the IC's ground.
4 OUT power_out The regulator output voltage.
5 FLG output Active-low open-collector error flag output that indicates an output fault condition (output 5% below expected value) and can sink 10 mA.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
