Linear Technology Announces LT3020 VLDO Regulator

July 21, 2004 by Jeff Shepard

Linear Technology Corp. (LTC, Milpitas, CA) announced its LT3020 very-low-dropout-voltage (VLDO) regulator with an input-voltage capability down to 0.9 V. The LT3020 has a VLDO of 150 mV while delivering up to 100 mA of output current. The LT3020 can operate across the entire voltage range of both single-cell alkaline and nickel-metal hydride (1.4 V to 0.9 V) batteries. The LT3020 offers micropower operation with only 120 µA of quiescent current and less than 3 µA in shutdown, maximizing run time in battery-powered, hand-held applications.

The LT3020 regulator optimizes stability and transient response with low ESR ceramic output capacitors as small as 2.2 µF. Other LT3020 features include 0% line regulation and 0.2% load regulation. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis, and reverse-current protection. The LT3020 regulator is available in a low-profile (0.75 mm), eight-lead DFN (3 mm x 3 mm) package with an exposed pad and an eight-lead MSOP package.

The LT3020EDD eight-lead DFN and the LT3020EMS8 (MSOP-8) are available from stock. Pricing for 1,000-piece quantities starts at $1.50 each for both package options.
