XC6219B332MR

UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

XC6219B332MR from UMW, in a SOT-23-5. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Regulator input supply. Operating range 1.8V to 7V (absolute max 9V). Bypass to VSS with a 10µF ceramic capacitor (Ci).
2 VSS power_in Ground / negative supply reference for the regulator.
3 CE input Chip enable (active high). VCEH ≥ 1.6V enables the regulator; VCEL ≤ 0.5V (e.g. tied to VSS) shuts it down (turn-off current typ 0.1µA). CE input current ≤0.5µA for VCE = 0V to VIN. Do not leave floating.
4 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically bonded to the die.
5 VOUT power_out Regulated 3.3V output (±2.5%). Delivers up to 300mA typical with Vin=4.3V. Requires a 10µF ceramic output capacitor (Co) to VSS. Dropout ~35mV at 10mA, ~280mV at 100mA.
