BL8074CC3TR12

BL(Shanghai Belling) · Linear Voltage Regulators (LDO) · SOT-89-3

BL8074CC3TR12 from BL(Shanghai Belling), in a SOT-89-3. 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 GND power_in Ground pin of the regulator, common return for input and output capacitors.
2 VDD power_in Supply voltage input; operating input range is 1.5V to 6V (recommended max 6V, absolute maximum 8V).
3 VOUT power_out Regulated output voltage (1.2V to 5.0V in 100mV steps, ±2% accuracy) delivering up to 800mA maximum output current.
