LT3012
250mA, 4V to 80V
Low Dropout
Micropower Linear Regulator
DESCRIPTION
The LT
®
3012 is a high voltage, micropower low dropout
linear regulator. The device is capable of supplying 250mA of
output current with a dropout voltage of 400mV. Designed
for use in battery-powered or high voltage systems, the low
quiescent current (40μA operating and 1μA in shutdown)
makes the LT3012 an ideal choice. Quiescent current is
also well controlled in dropout.
Other features of the LT3012 include the ability to operate
with very small output capacitors. The regulator is stable
with only 3.3μF on the output while most older devices
require between 10μF and 100μF for stability. Small ce-
ramic capacitors can be used without any need for series
resistance (ESR) as is common with other regulators.
Internal protection circuitry includes reverse-battery
protection, current limiting, thermal limiting and reverse
current protection.
The device is available with an adjustable output with a
1.24V reference voltage. The LT3012 regulator is available
in the 16-lead TSSOP and 12 pin low profile (0.75mm)
(4mm
×
3mm) DFN packages with an exposed pad for
enhanced thermal handling capability.
