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

CJ6211A12N from Changjing, in a SOT-23. 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 VSS power_in Ground / negative supply reference for the regulator.
2 VOUT power_out Regulated output. Fixed 1.2V nominal (per '12' MPN suffix); rated 500mA min / 700mA typ output current when VOUT >= 1.8V (300mA min / 500mA typ for VOUT >= 0.8V). Requires a >=1µF ceramic output capacitor. Internally current-limited and short-circuit protected (ISHORT ~= 100mA when VOUT is shorted to VSS).
3 VIN power_in Unregulated power input. Operating range 1.8V to 6.0V (absolute max -0.3V to 7V). Requires a >=1µF ceramic input capacitor. Typical dropout 55mV at IOUT=100mA (VOUT=3.3V).
