LT3011

50mA, 3V to 80V Low

Dropout Micropower Linear

Regulator with PWRGD

DESCRIPTION

FEATURES

The LT^®3011 is a high voltage, micropower, low dropout

linearregulator.Thedeviceiscapableofsupplying50mAof

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.

Wide Input Voltage Range: 3V to 80V

Low Quiescent Current: 46μA

Low Dropout Voltage: 300mV

Output Current: 50mA

PWRGD Flag with Programmable Delay

No Protection Diodes Needed

Adjustable Output from 1.24V to 60V

1μA Quiescent Current in Shutdown

The LT3011 includes a PWRGD ﬂag to indicate output

regulation. The delay between regulated output level and

ﬂag 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.

Smallceramiccapacitorscanbeusedwithouttheaddition

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.

Stable with 1μF Output Capacitor

Stable with Ceramic, Tantalum, and Aluminum

Capacitors

Reverse-Battery Protection

No Reverse Current Flow from Output to Input

Thermal Limiting

Thermally Enhanced 12-Lead MSOP and

10-Pin (3mm × 3mm) DFN Packages

APPLICATIONS

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 proﬁle (0.75mm)

10-pin (3mm × 3mm) DFN package, both providing excel-

lent thermal characteristics.
