LDO Regulator Handles Very Low Input Voltage

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.
