MIC5253-3.3YC5-TR

Microchip Tech · Linear Voltage Regulators (LDO) · SC-70-5

MIC5253-3.3YC5-TR from Microchip Tech, 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 Enable/shutdown input, CMOS compatible: logic high = enable, logic low = shutdown; do not leave open.
4 BYP passive Reference bypass: connect an external 0.01µF ≤ CBYP ≤ 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 (max recommended ESR 300mΩ) for stability.
