An input voltage as low as 0.9V can operate the LT3020 very low dropout voltage regulator (VLDO) enabling it to work with the entire range of single-cell alkaline and NiMH batteries (1.4V to 0.9V). Dropout voltage is 150 mV and output drive current is 100 mA. The low dropout voltage optimizes battery run time in single-cell applications having a low VIN to VOUT differential. For battery-powered, portable applications, the regulator draws just 120 µA of quiescent current and less than 3 µA in shutdown. Line regulation is 0% and load regulation, 0.2% from 0 to 100 mA. Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting with hysteresis, and reverse current protection. Two packaging styles are available: a low-profile (0.74 mm) 8-lead DFN (3 mm x 3 mm) with an exposed pad, and an 8-lead MSOP. Pricing for both package types starts at $1.50 each/1,000.
