This device supplies 500m A of output current with a typical dropout voltage of 160m V. The LT3021 is ideal for low input voltage to low output voltage applications, providing parable electrical efficiency to that of a switching regulator. The LT3021 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 3.3µF. Other LT3021 Features include 0.05% typical line regulation and 0.2% typical load regulation. In shutdown, quiescent current typically drops to 3µA. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis, and reverse-current protection. The LT3021 is available as an adjustable output device with an output range down to the 200m V reference. Three fixed output voltages, 1.2V, 1.5V and 1.8V, are also available. The LT3021 regulator is available in the low profile (0.75mm) 16-pin (5mm × 5mm) DFN package with exposed pad and the 8-lead SO package. , LTC and LT are registered trademarks of Linear Technology Corporation.
