GENERAL DESCRIPTION

The LT3046 is a high-performance, low-dropout linear

regulator featuring Analog Devices, Inc. ultra-low noise

and ultra-high PSRR architecture for powering noisesensitive

applications. Designed as a precision current

reference followed by a high-performance voltage

buffer, the LT3046 can be easily paralleled to further

reduce noise, increase output current, and spread heat

on the PCB.

The device supplies 200mA at a typical 300mV dropout

voltage. Operating quiescent current is nominally

3.7mA and drops to 26μA in shutdown. The LT3046’s

wide output-voltage range (0.2V to 19V) while

maintaining unity-gain operation provides virtually

constant output noise, PSRR, bandwidth, and load

regulation, independent of the programmed output

voltage. Additionally, the regulator features

programmable current limit, fast start-up capability,

and programmable power good to indicate output

voltage regulation.

Built-in protection includes reverse-battery protection,

reverse-current protection, internal current limit with

foldback and thermal limit with hysteresis. The LT3046

is available in a thermally enhanced, 12-lead, 3mm ×

3mm, DFN package.
