MIC37302WU-TR

Microchip Tech · Linear Voltage Regulators (LDO) · TO-263-5

MIC37302WU-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 Enable input, CMOS/TTL compatible: logic high = enable, logic low = shutdown (VEN ≤ 0.8V shutdown, ≥ 2.25V enable); do not leave floating.
2 VIN power_in Input voltage supplying current to the output power device, operating range 2.25V to 6.0V.
3 GND power_in Ground; the TAB is connected to ground.
4 VOUT power_out Regulator output, 3A minimum output current, adjustable from 1.24V to 5.5V.
5 ADJ input Adjustable regulator feedback input (1.240V reference) connected to a resistor voltage divider.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
