LT3063 Series

45V V , Micropower,

Low Noise, 200mA LDO

with Active Output Discharge

DESCRIPTION

FEATURES

The LT^®3063 is a micropower, low dropout (LDO) linear

regulator that operates over a 1.6V to 45V supply range

and is available in a series of fixed output and adjustable

versions. The device supplies 200mA of output current

with a typical dropout voltage of 300mV. A single external

capacitor provides programmable low noise reference

performance and output soft-start functionality. The

LT3063’s quiescent current is merely 45μA and provides

fast transient response with a minimum 3.3μF output ca-

pacitor. In shutdown, quiescent current is less than 3μA

and the reference soft-start capacitor is reset.

Input Voltage Range: 1.6V to 45V

Output Current: 200mA

Output Noise

The LT3063 features an NMOS pull-down that discharges

the output if SHDN or IN is driven low.

APPLICATIONS

The LT3063 is available in fixed output voltages of 3.3V

and 5V, and as an adjustable device with an output voltage

range from the 600mV reference up to 19V. The LT3063

is offered in the thermally enhanced 8-lead 2mm × 3mm

DFN and MSOP packages.
