CJ6109B33M

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

CJ6109B33M 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 VIN power_in Power input pin; the datasheet specifies an input voltage range of 1.6 V to 6.0 V.
2 VSS power_in Ground pin; all voltages are referenced to the network ground terminal.
3 CE input Chip enable pin; a level of 1.5 V to VIN enables the regulator and 0.3 V maximum shuts it down, with shutdown current of 1.0 µA max when CE = VSS.
4 NC unconnected No connection.
5 VOUT power_out Regulated output pin; the datasheet lists 1.0 A typical guaranteed output current and recommends a 4.7 µF or larger output capacitor.
