CJ86L05

Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L

CJ86L05 from Changjing, in a SOT-89-3L. 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 VOUT power_out Regulated output of the 5 V ±2% regulator, supplying up to 250 mA output current.
2 GND power_in Ground terminal (labeled VSS in the block diagram) to which all voltages are referenced.
3 VIN power_in Regulator input with a supply range of 2.5 V to 45 V (absolute maximum -0.3 V to 50 V).
