XC6219B252MR

UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-5

XC6219B252MR from UMW, in a SOT23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply pin. Operating range 1.8V to 7V, absolute maximum 9V. Bypass to VSS with a 10µF ceramic capacitor close to the pin.
2 VSS power_in Device ground reference (0V).
3 CE input Chip Enable (active high). VCEH = 1.6V min (up to VIN) enables the regulator; VCEL = 0 to 0.5V places the device in shutdown (turn-off current typ. 0.1µA). CE input current ≤0.5µA. Do not leave floating.
4 NC unconnected No internal connection. Leave open or tie as convenient for the PCB layout.
5 VOUT power_out Regulated output, fixed 2.5V ±2.5% for XC6219B252MR. Supplies up to 300mA (typ) with a 280mV typ dropout at 100mA. Requires a 10µF ceramic output capacitor for stability.
