Introduction

The RT9068 family are high voltage (60V operation), low quiescent current low dropout linear regulators capable of supplying 50mA of output current with a maximum dropout voltage of 300mV. The low quiescent and shutdown currents (30μA operating and 2μA shutdown) are ideal for use in battery-powered and/or high voltage systems. Ground current is well-controlled in all conditions, including dropout. The RT9068 family operates with any reasonable output capacitors including 1μF low-ESR ceramic types and features excellent line and load transient responses. Internal protection circuitry includes reverse-battery protection, current limiting, thermal shutdown, and reverse current protection. Output voltage accuracy is ±2% over the entire line and load range. These devices are available in 3 fixed-output versions (2.5V, 3.3V, 5V) as well as a version that supports an adjustable output voltage (1.25V to 60V). All versions come in SOP-8 and MSOP-8 packages with an exposed pad for high power dissipation.
