● DESCRIPTIO VIN Range: 0.9V to 10V Dropout Voltage: 160mV Typical Output Current: 500mA Adjustable Output (VREF = VOUT(MIN) = 200mV) Fixed Output Voltages: 1.2V, 1.5V, 1.8V Stable with Low ESR, Ceramic Output Capacitors (3.3µF Minimum) 0.2% Load Regulation from 0mA to 500mA Quiescent Current: 120µA (Typ) 3µA Typical Quiescent Current in Shutdown Current Limit Protection Reverse-Battery Protection No Reverse Current Thermal Limiting with Hysteresis 16-Pin DFN (5mm × 5mm) and 8-Lead SO Packages The LT®3021 is a very low dropout voltage (VLDOTM) linear regulator that operates from input supplies down to 0.9V. This device supplies 500mA of output current with a typical dropout voltage of 160mV. 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.
