XC6219B122MR-MS

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

XC6219B122MR-MS from MSKSEMI, in a SOT-23-5. 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 Power input pin. Absolute maximum supply voltage -0.3V to 8V. Recommended input capacitor CIN=10uF close to the pin for stable operation.
2 GND power_in Ground/VSS reference for the regulator. Keep resistance low between VIN and VSS wiring.
3 CE input Chip Enable pin. CMOS hysteresis inverter input; drive to VIN to enable and to VSS to shut down (standby current ~0.1uA). Should be tied to a valid VIN or VSS level, not left floating.
4 NC unconnected No Connection. Leave open or tie to ground; not internally bonded.
5 VOUT power_out Regulated output pin. Fixed 1.2V (±2%) for the -B122 option, up to 350mA typical output current. Requires an output capacitor CL≥10uF placed close to VOUT/GND for phase compensation stability.
