MIC5219-3.3YMM-TR

Microchip Tech · Linear Voltage Regulators (LDO) · MSOP-8

MIC5219-3.3YMM-TR from Microchip Tech, in a MSOP-8. 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 is CMOS-compatible: logic-high (>2 V) enables the regulator, while logic-low or open puts it in shutdown.
2 IN power_in Supply input; a 1 µF capacitor from IN to GND is recommended if there is more than 10 inches of wire to the AC filter capacitor or if a battery is the input.
3 OUT power_out Regulator output; an output capacitor between OUT and GND is required to prevent oscillation (1 µF minimum without CBYP, 2.2 µF minimum with 470 pF CBYP, ESR about 1 Ω or less).
4 BYP passive Reference bypass for the fixed-voltage version: connect an external 470 pF capacitor to GND to reduce output noise, or leave open.
5 GND power_in Ground; MSOP-8 pins 5 through 8 are internally connected to each other.
6 GND power_in Ground; MSOP-8 pins 5 through 8 are internally connected to each other.
7 GND power_in Ground; MSOP-8 pins 5 through 8 are internally connected to each other.
8 GND power_in Ground; MSOP-8 pins 5 through 8 are internally connected to each other.
