250mA LDO Withstands 80V Input & Operates -55°C to +125°C
MILPITAS, CA – February 26, 2009 – 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
LT3013MPFE in the TSSOP package is priced at $6.50 each in 1,000-piece quantities.
