Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6101B20M 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 | IN | power_in | Input to the device; place the recommended input capacitor as close as possible to the IN and GND pins to obtain the best transient response and minimize input impedance. Input voltage range is 1.8V to 6.0V. |
| 2 | GND | power_in | Regulator ground. |
| 3 | EN | input | Enable pin: drive high to enable the device and low to turn it off; do not float this pin, and if enable is not needed, connect EN to IN. |
| 4 | NC | unconnected | No internal connection; this pin can float, but connecting it to GND gives the device better thermal performance. |
| 5 | OUT | power_out | Regulator output; place the recommended output capacitor between OUT and GND as close as possible to the pins to maintain stability and obtain the best transient response. |
