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. |
