Description

The LT3062 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 LT3062’s quiescent current is merely 45μA and provides fast transient response with a minimum 3.3μF output capacitor. In shutdown, quiescent current is less than 1μA and the reference soft start capacitor is reset.The LT3062 optimizes stability and transient response with low ESR, ceramic output capacitors. The LT3062 does not require the addition of ESR as is common with other regulators.Internal protection circuitry includes reverse-battery protection, reverse-output protection, reverse-current protection, current limit with foldback and thermal shutdown.The LT3062 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 40V. The LT3062 is offered in the thermally enhanced 8-lead 2mm × 3mm DFN and MSOP packages.ApplicationsBattery Powered SystemsAutomotive Power SuppliesIndustrial Power SuppliesAvionic Power SuppliesPortable Instruments
