MIC5209-5.0YU

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

MIC5209-5.0YU 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-compatible: logic-high (>2.0V) enables the regulator, logic-low (≤0.4V) shuts it down; connect to IN if not used.
2 IN power_in Supply input, operating range +2.5V to +16V (absolute maximum -20V to +20V).
3 GND power_in Ground pin, internally connected to the TAB.
4 OUT power_out Regulated 5.0V output (fixed version) requiring an output capacitor (1 µF minimum without CBYP, 2.2 µF minimum with 470 pF CBYP) to GND for stability.
5 BYP passive Reference bypass for fixed-voltage versions: connect an external 470 pF capacitor to GND to reduce output noise, or leave open.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
