Compact linear regulator with thermal resistance
A Linear Technology product story
Edited by the Electronicstalk editorial team Dec 21, 2010
Linear Technology has produced a wider-temperature-range version of the LT3010, a high-voltage, micropower linear regulator for avionics, military, industrial, automotive, RF and telecom applications.
The high-reliability MP grade features operation from -55C to +125C and a low-dropout regulator that can deliver up to 50mA of continuous output current.
The LT3010 is a high-voltage micropower, low dropout regulator that can deliver up to 50mA of continuous output current
It operates at input voltages from three to 80V, delivering output voltages as low as 1.275V and providing a fixed 5V output.
Low quiescent current of 30uA (operating) and 1uA (in shutdown), make it suitable for battery-powered 'keep alive' systems that require optimum run time.
For high voltage applications that require large input-to-output voltage differentials, the LT3010/-5 offers a compact solution.
Its thermally enhanced MSOP-8 package offers thermal resistance equivalent to much larger conventional packages.
Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse-current protection.
