LT3021/LT3021-1.2/ LT3021-1.5/LT3021-1.8 - 500mA, Low Voltage, Very Low Dropout Linear 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 200mV 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.
