■GENERAL DESCRIPTION
On resistance even where low output voltages to achieve high efficiency of the output current. The series is suited for the
application which requires low dropout voltage operation. The series consists of a voltage reference, an error amplifier, a driver
transistor, a current limiter, a fold back circuit, a thermal shutdown (TSD) circuit, a Under Voltage Lock Out (U.V.L.O.) and a
phase compensation circuit.
