BAxxBC0 Series(Fixed) BAxxBC0W Series(Fixed) BA00BC0WCP-V5(Variable)

●General Description

The BAxxBC0 are low-saturation regulators with an output current of 1.0 A and an output voltage accuracy of ±2%. A broad
output voltage range is offered, from 1.5V to 10V, and built-in overcurrent protec tion and thermal shutdown (TSD) circuits
prevent damage due to short-circuiting and overloading, respectively.

Broad output range available: 1.5 V -10 V
(BAxxBC0 series)

 Low saturation-voltage type with PNP output
 Built-in overcurrent protection circuit
 Built-in thermal shutdown circuit
 Integrated shutdown switch (BAxxBC0WT,

BAxxBC0WT-5, or BAxxBC0WFP Series,
BA00BC0WCP-V5)

●Key Specifications
