CJ6101B28M

Changjing · Linear Voltage Regulators (LDO) · SOT-23-5L

CJ6101B28M from Changjing, in a SOT-23-5L. 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 IN power_in Input to the device; operating input voltage range is 1.8V to 6.0V.
2 GND power_in Regulator ground.
3 EN input Enable pin, logic high to enable and logic low to disable (VEN H min 1.5V, VEN L max 0.3V); do not float the pin.
4 NC unconnected Not connected.
5 OUT power_out Output of the regulator, providing up to 300mA output current.
