Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6205B25M from Changjing, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Unregulated positive power input. Operating range 2.0 V to 6.0 V; absolute max VSS-0.3 V to VSS+7 V. Bypass to VSS with 1 uF ceramic close to the pin. |
| 2 | VSS | power_in | Device ground / negative supply return. Common reference for VIN, VOUT and CE. |
| 3 | CE | input | TTL chip-enable input. High enables the regulator (VCE-H min 1.5 V, up to VIN); Low shuts it down (VCE-L max 0.3 V, ISTBY <=0.1 uA). On the 'B' variant an internal pull-down holds the part off if CE is left floating and a COUT discharge resistor pulls VOUT down when disabled. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to VSS. |
| 5 | VOUT | power_out | Regulated 2.5 V output (accuracy typ. +/-2%, VOUT0.98 to VOUT1.02). 500 mA typ output current, 100 mA short-circuit current limit. Requires 1 uF ceramic load cap; typical dropout 150 mV @150 mA. |
