CJ6300BM

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

CJ6300BM 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; input voltage range is 1.8V (or VOUT+VDO, whichever is greater) to 7.0V, absolute maximum VSS+8V.
2 VSS power_in Ground pin.
3 CE input Chip enable pin, active high: VCEH min 1.2V, VCEL max 0.3V, with built-in pull-down resistor, and shutdown current below 0.1µA.
4 FB input Feedback pin used to set the output voltage via an external divider, with VFB = 0.6V typical and VOUT = 0.6V × (1 + R1/R2).
5 VOUT power_out Regulated output pin supplying up to 500mA, adjustable 0.6V to 5.5V, stable with a 1µF ceramic capacitor.
