RT9068-50GSP

The RT9068-50GSP from Richtek is a low dropout (LDO) voltage linear regulator in 8 pin SOP package. This high voltage (60V operation), low quiescent current low dropout linear regulator is 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 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, overtemperature protection, current limiting, thermal shutdown and reverse current protection. Output voltage accuracy is ±2% over the entire line and load range. It is typically used in low current, high voltage regulators, battery powered applications, telecom and datacom applications.
