Low Voltage Variable Output LDO Regulator
BA00BC0WFP/WT
Description
BA00BC0WFP/WT is a PNP output LDO
regulator IC with the output current of 1A
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.
