BL8568GCB5ATR15

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

BL8568GCB5ATR15 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. Recommended operating range 2.0V-6V (absolute max 8V). A 1µF ceramic input capacitor to Vss is recommended in all application circuits.
2 Vss power_in Device ground / negative supply return. Reference for Vin, Vout and CE. When CE is tied to Vss the device enters standby (Istandby = 0.1µA typ).
3 CE input Chip Enable logic input. Vceh ≥ 1.0V (up to Vin) enables the regulator; Vcel ≤ 0.5V disables it and engages the ~1.5kΩ output discharge. Integrated ~500kΩ internal pull-down (Rcepd) - do not leave floating in noisy environments; drive from a valid logic source.
4 NC unconnected No Connection. Leave floating or, for best PCB robustness, tie to Vss. Not internally bonded.
5 Vout power_out Regulated output voltage (1.5V for the -15 ordering suffix). Delivers up to 300mA (typ) with 500mA current limit; dropout 65mV @100mA / 195mV @300mA at Vout=3.3V. Requires a 1µF ceramic output capacitor to Vss for stability. When CE is low, Vout is actively discharged through the internal ~1.5kΩ resistor.
