MIC5319-3.3YD5-TR

Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOT-23-5

MIC5319-3.3YD5-TR from Microchip Tech, in a TSOT-23-5. 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 VIN power_in Supply input; the datasheet specifies an input voltage range of 2.5V to 5.5V (absolute maximum 6V).
2 GND power_in Ground pin.
3 EN input Active-high enable input: High = ON, Low = OFF; must not be left floating, with VIL ≤ 0.2V and VIH ≥ 1.2V.
4 BYP passive Reference bypass: connect an external 0.1µF capacitor to GND for reduced output noise; may be left open.
5 VOUT power_out Regulated output voltage; the datasheet requires an output capacitor of 2.2µF or greater (low-ESR ceramic) for stability.
