BL8077CKETR33

BL(Shanghai Belling) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN1x1-4

BL8077CKETR33 from BL(Shanghai Belling), in a DFN1x1-4. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated output voltage pin (fixed 1.2V/1.8V/2.5V/2.8V/3V/3.3V versions, up to 300mA max output current; 1uF output capacitor recommended).
2 GND power_in Ground pin; the thermal pad is also connected to GND.
3 CE input Chip enable, high active with no pull-down: CE low level 0 to 0.4V shuts down, high level 1.5 to 5.5V enables; do not leave open, tie to VIN or GND.
4 VIN power_in Supply voltage input, operating range 1.8V to 5.5V (absolute maximum 8V); 1uF input capacitor recommended.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
