XC6220B251MR

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

XC6220B251MR from TDSEMIC, in a SOT-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 Power input; absolute maximum input voltage is 8 V (7.0 V maximum input voltage in the selection table).
2 VSS power_in Ground terminal.
3 CE input Chip enable input that turns the output on or off, and shutdown quiescent current is typically 0.1 uA.
4 NC unconnected No connection (empty pin).
5 VOUT power_out Regulated output (2.5 V for the 251 option, ±2.5% tolerance); output current is rated to 500 mA absolute maximum and the voltage range is Vss-0.3 V to Vin+0.3 V.
