BL8568GCB5ATR18 from BL Shanghai Belling, in a SOT-23-5. 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 | Supply voltage input. Operating range 2.0 V to 6.0 V (absolute max 8 V). A 1 uF input capacitor to Vss is recommended. |
| 2 | Vss | power_in | Device ground / negative supply reference. Common return for Vin, Vout, and CE. |
| 3 | CE | input | Chip Enable input. VCEH ≥ 1.0 V (up to Vin) enables the regulator; VCEL ≤ 0.5 V disables it (shutdown mode, Istandby ≈ 0.1 uA). Internal ~500 kΩ pull-down to Vss; when CE is low the output is actively discharged through an internal ~1.5 kΩ resistor. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to Vss for best mechanical/thermal reliability. |
| 5 | Vout | power_out | Regulated voltage output (1.8 V for the '18' suffix). Delivers up to 300 mA typ. (500 mA current-limit). A 1 uF output capacitor to Vss is recommended for stability; dropout ≈ 65 mV @ 100 mA typ. (Vout ≥ 2.8 V). |
