DESCRIPTION

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 flag to

indicate output regulation. The delay between regulated

output level and flag 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 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 LT3013 regulator is available

in the thermally enhanced 16-lead TSSOP and the low

profile (0.75mm), 12-pin (4mm × 3mm) DFN package,

both providing excellent thermal characteristics.
