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. |
