ADI LT3060EDC#TRMPBF

正45V100mA

Overview

The LT3060EDC series are micropower, low dropout voltage (LDO) linear regulators that operate over a 1.6V to 45V input supply range. The devices supply 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.

Internal protection circuitry includes reverse-battery protection, reverse-output protection, reverse-current protection, current limit with foldback and thermal shutdown. The LT3060EDC series are available in fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V and 15V, and as an adjustable voltage regulator with an output voltage range from the 600mV reference to 44.5V. The LT3060EDC regulators are offered in the thermally enhanced 8-lead TSOT-23 and 8-lead (2mm × 2mm × 0.75mm) DFN packages.
