DESCRIPTION
50mA, 3V to 80V
Low Dropout
Micropower Linear Regulator
The LT
®
3010 is a high voltage, micropower low dropout
linear regulator. The device is capable of supplying 50mA
output current with a dropout voltage of 300mV. Designed
for use in battery-powered or high voltage systems, the low
quiescent current (30µA operating and 1µA in shutdown)
makes the LT3010 an ideal choice. Quiescent current is
also well controlled in dropout.
Other features of the LT3010 include the ability to operate
with very small output capacitors. The regulators are stable
with only 1µF on the output while most older devices re-
quire 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 in a fixed output voltage of 5V and
as an adjustable device with a 1.275V reference voltage.
The LT3010 regulator is available in the 8-lead MSOP pack-
age with an exposed pad for enhanced thermal handling
capability.
