DESCRIPTIO
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. De-
signed for use in battery-powered or high voltage sys-
tems, 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 neces-
sary addition of ESR as is common with other regulators.
Internal protection circuitry includes reverse-battery pro-
tection, current limiting, thermal limiting and reverse
current protection.
The device is available as an adjustable device with a 1.22V
reference voltage. The LT3014 regulator is available in the
5-lead ThinSOT and 8-lead DFN packages.
