RT9072B

RT9072A/B 80V, Low Dropout Voltage Linear Regulator General Description 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. 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. The RT9072A/B has an adjustable output voltage (1.25V to 60V). It is available in the SOT-23-5 package.
