Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

CJ6205A28M from Changjing, in a SOT-23-3L. 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 VSS power_in Ground pin; the absolute maximum input voltage is specified as VSS -0.3 to VSS+7 V and the output voltage as VSS -0.3 to VIN+0.3 V, both referenced to this pin.
2 VOUT power_out Regulated output pin; output current is rated up to 500 mA in the electrical characteristics (600 mA absolute maximum), and output voltage is 1.2 to 5.0 V (2.8 V for CJ6205A28M).
3 VIN power_in Power input pin; the operating input voltage is 2.0 V to 6.0 V, and the absolute maximum input is VSS+7 V.
