Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6205B28M 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; the datasheet gives an operating input voltage of 2.0 V to 6.0 V and an absolute maximum input of VSS-0.3 V to VSS+7 V. |
| 2 | VSS | power_in | Ground pin, the regulator reference; the output absolute maximum is referenced to VSS (VSS-0.3 V to VIN+0.3 V). |
| 3 | CE | input | Chip enable pin for TTL-logic shutdown control; the datasheet gives VCE high at a minimum of 1.5 V (up to VIN) and VCE low at a maximum of 0.3 V. |
| 4 | NC | unconnected | No connection pin, listed as No Connection in the datasheet pin table. |
| 5 | VOUT | power_out | Regulated output pin; output voltage is 1.2 V to 5.0 V per the features list, and output current is rated at 500 mA. |
