BL8568GCB5ATR18

BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

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).
