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

BL8568CB5ATR18 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 2.0V-6V (absolute max 8V). Recommend 1uF ceramic decoupling capacitor to Vss.
2 Vss power_in Ground return pin for the regulator.
3 CE input Chip enable. Drive high (Vceh ≥ 1.5V, up to Vin) to enable the regulator; drive low (Vcel ≤ 0.25V) to enter shutdown (Istandby 0.1uA typ) and activate the 1.5kΩ output discharge path. Internally pulled down through ~5MΩ (Rcepd).
4 NC unconnected No internal connection. Leave floating or tie to ground on the PCB.
5 Vout power_out Regulated 1.8V output (±2% accuracy, 500mA max, 300mV typ dropout at 300mA). Requires 1uF ceramic output capacitor for stability. Actively discharged through ~1.5kΩ when CE is low.
