DESCRIPTION
The
LT
®
3014B
is a high voltage, micropower low drop-
outlinear 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 sys-
tems, the low quiescent current (7µA operating) makes
the LT3014B an ideal choice. Quiescent current is also
well controlled in dropout.
Other features of the LT3014B 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 protec-
tion circuitry includes reverse-battery protection, current
limiting, thermal limiting and reverse current protection.
The device is available as an adjustable device with a 1.22V
reference voltage. The LT3014B regulator is available in
the 5-lead ThinSOT and 8-lead DFN packages.
