DESCRIPTION
The LT
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, current limit with foldback and thermal shutdown.
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.
