TYPICAL APPLICATION
DESCRIPTION
250mA, 4V to 80V
Low Dropout Micropower
Linear Regulator with PWRGD
The LT
®
3013 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 (65µA operating and 1µA in shutdown)
makes the LT3013 an ideal choice. Quiescent current is
also well controlled in dropout.
Other features of the LT3013 include a PWRGD fl ag to
indicate output regulation. The delay between regulated
output level and fl ag indication is programmable with
a single capacitor. The LT3013 also has 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 ceramic 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 LT3013 regulator is available
in the thermally enhanced 16-lead TSSOP and the low
profi le (0.75mm), 12-pin (4mm × 3mm) DFN package,
both providing excellent thermal characteristics.
