250mA LDO Withstands 80V Input & Operates -55°C to +125°C
Milpitas , CA, (PresseBox) -
Linear Technology Corporation announces a new high reliability (MP) grade, wider temperature range version of the LT3013, a micropower LDO with input voltage capability up to 80V. The MP grade device is offered in the TSSOP package and operates from -55°C to +125°C junction temperature, featuring low dropout voltage of only 400mV while delivering up to 250mA of output current. 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.
LT3013MPFE in the TSSOP package is priced at $6.50 each in 1,000-piece quantities. For more information, visit www.linear.com.
