RT9068

60V, 30μA I_Q, Low Dropout Voltage Linear Regulator

General Description

Features

^Wide Input Voltage Range : 4.5V to 60V

^Low Quiescent Current : 30μA Operating and 2μA

Shutdown

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 (30μAoperating and 2μAshutdown) are ideal for

use in battery-powered and/or high voltage systems.

Ground current is well-controlled in all conditions, including

dropout.

^Low Dropout Voltage : 300mV Maximum at 50mA

^Fixed (2.5V, 3.3V, 5V) and Adjustable (1.25V to 60V)

Versions



2% Output Tolerance

^Stable with 1μF Output Capacitor (Aluminum,

Tantalum or Ceramic)

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.

^Inherent Reverse-Current Protection (No diode

needed)

 −60V Reverse-Battery Protection

Applications

 Low Current, High Voltage Regulators

 Battery Powered Applications

 Telecom andDatacomApplications

 AutomotiveApplication

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.
