RT9072A/B

80V, Low Dropout Voltage Linear Regulator

General Description

Features

 Wide Input Voltage Range: 4.5V to 80V

 Low Quiescent Current : 23A Operating and 3A

Shutdown

The RT9072A/B is a high voltage (80V operation), low

quiescent current, low dropout linear regulator. The

device supplies 20mA output current with a maximum

dropout voltage of 230mV. Its low quiescent and

shutdown currents (23A operating and 3A shutdown)

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: 180mV (typical) at 20mA

 Adjustable (1.25V to 60V) Output Voltage

 2% Initial Output Tolerance

 3% Output Tolerance over Line, Load, Temperature

Range

 Stable with 1F Output Capacitor

 Stable with Aluminum, Tantalum or Ceramic

Capacitors

The RT9072A/B operates with any reasonable output

capacitors including 1F low-ESR ceramic types. It

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

±3% over the entire line, load, and temperature range.

 No Reverse-Current Protection Diode Needed

 80V Reverse-Battery Protection

 Internal Current Limit

 Internal Thermal Shutdown Protection

The RT9072A/B has an adjustable output voltage

(1.25V to 60V). It is available in the SOT-23-5 package.
