MIC29152WD-TR

Microchip Tech · Linear Voltage Regulators (LDO) · TO-252-5

MIC29152WD-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 CMOS compatible control input; logic-high = enable, logic-low = shutdown.
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 on D-PAK.
4 OUT power_out The regulator output voltage.
5 ADJ input Adjustable regulator feedback input connecting to the resistor divider placed from OUTPUT to GND to set the output voltage.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
