The wide VIN capability of 3.3V to 80V and adjustable output from 1.24V up to 60V makes it ideal for automotive, avionics, 48V telecom backup supplies and industrial control applications. With its very low quiescent current of 65uA (operating) and 1uA (shutdown), the LT3013 improves battery life in battery-powered memory “keep alive” systems that require extended run times. The LT3013’s PGood flag feature is programmable and indicates output regulation.

For high voltage applications that require large input-to-output differentials, the LT3013 offers a very compact and thermally effective solution. The thermally enhanced TSSOP package provides thermal resistances comparable to much larger conventional packages. The device operates with very small, low cost ceramic output capacitors, and is stable with only a 3.3uF output capacitor, compared to prior regulators of comparable output current and high voltage requiring 10uF to more than 100uF. These tiny external capacitors can be used without any necessary series resistance as is common with many other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and reverse-current protection.
