BA00BC0WF is a PNP output LDO
regulator IC with the output current of 0.5A
and a voltage accuracy of ± 2%.
Output voltage can be set (1.5V to 12V) by
external resistor. Over-current protection
circuit and thermal protection circuit are
incorporated to prevent IC from being
damaged by short and thermal break down.

• This product is not designed for protection against radioactive rays.
Designed Guarantee.(Outgoing inspection is not done all products.)
*1 All
characteristics are measured with a capacity across the input of 0.33µF and a capacity across the output of 0.22µF.
* Measurement
is done at Ta Tj, and variations in the parameter of all measurement(expect Temperature Coefficient of Output Voltage)caused by temperature change are not considered.
