DESCRIPTION
The LT®3014 is a high voltage, micropower low dropout linear
regulator. The device is capable of supplying 20mA of output
current with a dropout voltage of 350mV. Designed for use in
battery-powered or high voltage systems, the low quiescent current
(7μA operating and 1μA in shutdown) makes the LT3014 an ideal
choice. Quiescent current is also well controlled in dropout.
Other features of the LT3014 include the ability to operate with
very small output capacitors. The regulators are stable with only
0.47μF on the output while most older devices require between 10μF
and 100μF for stability. Small ceramic capacitors can be used
without the necessary addition of ESR as is common with other
regulators. Internal protection circuitry includes reverse-battery
protection, current limiting, thermal limiting and reverse current
protection.
