DESCRIPTION
50mA, 3V to 80V Low
Dropout Micropower Linear
Regulator with PWRGD
The LT
®
3011 is a high voltage, micropower, low dropout
linear regulator. The device is capable of supplying 50mA of
output current with a dropout voltage of 300mV. Designed
for use in battery-powered high voltage systems, the low
quiescent current (46μA operating and 1μA in shutdown)
is well controlled in dropout, making the LT3011 an ideal
choice.
The LT3011 includes 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 LT3011 also has the ability to operate with very small
output capacitors; it is stable with only 1μF on the output.
Small ceramic capacitors can be used without the addition
of any 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 LT3011 features an adjustable output with a 1.24V
reference voltage. The device is available in the thermally
enhanced 12-lead MSOP and the low profi le (0.75mm)
10-pin (3mm × 3mm) DFN package, both providing excel-
lent thermal characteristics.
