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. |
