MIC5253-1.8YC5-TR

MICROCHIP TECHNOLOGY / ATMEL · Global Sourcing Parts · SC-70-5

MIC5253-1.8YC5-TR from MICROCHIP TECHNOLOGY / ATMEL, in a SC-70-5. 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 IN power_in Supply input, operating range 2.7V to 5.5V, requires a 1µF capacitor to ground for stability.
2 GND power_in Ground.
3 EN input CMOS-compatible enable/shutdown input, logic high (≥1.6V) enables and logic low (≤0.4V) shuts down the regulator; do not leave open.
4 BYP passive Reference bypass pin; connect an external 0.01µF to 1.0µF capacitor to GND to reduce output noise, may be left open.
5 OUT power_out Regulator output, requires 1µF or greater output capacitor for stability, 100mA continuous output current.
