TYPICAL APPLICATION

DESCRIPTION

Low Noise, 100mA Low

Dropout, Linear Regulator

linear regulator that operates over a 1.6V to 45V input

supply range. The device supplies 100mA 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

LT3060’s quiescent current is merely 40μA and provides

fast transient response with a minimum 2.2μF output

capacitor. In shutdown, quiescent current is less than 1μA

and the reference soft-start capacitor is reset.

The LT3060 optimizes stability and transient response

with low ESR, ceramic output capacitors. The regulator

does not require the addition of ESR as is common with

other regulators. The LT3060 typically provides 0.1% line

regulation and 0.03% load regulation.

Internal protection circuitry includes reverse-battery

protection, reverse-output protection, reverse-current

protection,currentlimitwithfoldbackandthermalshutdown.

The LT3060 is an adjustable voltage regulator with an output

voltage range from the 600mV reference to 44.5V. The

LT3060 is offered in the thermally enhanced 8-lead TSOT-23

and 8-lead (2mm × 2mm × 0.75mm) DFN packages.
