Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6211B28M 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 1.8 V to 6.0 V, absolute max 7 V. Bypass with a 1 µF ceramic CIN to VSS close to the pin. |
| 2 | VSS | power_in | Ground / negative supply return for the regulator. All voltages are referenced to this network ground. |
| 3 | CE | input | TTL-logic chip-enable input, active high. VCE high threshold ≥1.5 V (up to VIN), VCE low ≤0.3 V. B-variant integrates a pull-down resistor so the part defaults off when CE floats; driving CE low enables the internal N-channel discharge FET across VOUT-VSS (≈60 Ω typ.). |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to VSS on the board. |
| 5 | VOUT | power_out | Regulated output, 2.8 V for the '28' ordering code. Up to 700 mA (VOUT ≥ 1.8 V) / 500 mA (VOUT ≥ 0.8 V). Requires a 1 µF ceramic COUT to VSS; internal current limit and short-circuit protection to ~100 mA short current. |
