Linear Technology Announces LT3014 LDO Regulator

April 04, 2005 by Jeff Shepard

Linear Technology Corp. (LTC, Milpitas, CA) announced its new LT3014 high-voltage, micropower, low dropout regulator, which is capable of delivering 20 mA output current. The LT3014 operates with a continuous input-voltage range of 3 V to 80 V, and generates output voltages from 1.22 V to 60 V with a low dropout of 350 mV, making it suitable for automotive, 48 V telecom backup supplies, battery-powered memory "keep alive" systems and industrial control applications.

The LT3014 offers an ultra-low quiescent current of 7 µA (operating) and 1 µA (in shutdown), stability with only 0.47 µF on the output, a low-profile (0.75 mm) 3 mm x 3 mm DFN and ThinSOT™ package, reverse-battery protection, current-limiting protection, thermal limiting protection, and reverse-current protection. The LT3014HV version will survive 100 V input-voltage transients for a 2 µs duration.

The LT3014EDD and LT3014ES5 standard versions and the corresponding LT3014HVEDD and LT3014HVES5 high-voltage versions are available from stock in an eight-lead, 3 mm x 3 mm DFN package and in a five-lead ThinSOT-23 package. Pricing starts at $1.19 for the standard versions and $1.36 for the HV versions for 1,000-piece quantities.
