LDO Regulator With Shutdown Circuit
BA00BC0WF
Description
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.
