Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6206B30M 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 power input. Operating range 2.0V to 7.0V (absolute max VSS-0.3V to VSS+8V). Bypass with a 1µF low-ESR ceramic input capacitor (CIN) close to the pin. |
| 2 | VSS | power_in | Ground return / device negative supply. Common return for VIN, VOUT and CE reference. |
| 3 | CE | input | TTL-compatible chip-enable (shutdown) input. CE ≥ 1.5V (VCE"H") enables the regulator; CE ≤ 0.3V (VCE"L") or CE tied to VSS disables it, dropping standby current to <0.1µA. Must not be left floating. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net; no electrical function on the SOT-23-5L variant. |
| 5 | VOUT | power_out | Regulated 3.0V output (±2% typical), rated 300mA continuous, 600mA absolute max. Bypass with a 1µF low-ESR ceramic output capacitor (COUT) for stability and transient response. Short-circuit protected (I_SHORT ≈ 50mA when VOUT shorted to VSS). |
