Product Details

Demonstration circuit 932A is an adjustable 1A linear regulator featuring LT3022. The LT3022 is a very low dropout voltage (VLDO™) linear regulator that operates from input supplies down to 0.9V. The device supplies 1A of output current with 145mV typical dropout voltage. The LT3022 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to a switching regulator. The demo board has an input voltage range from 1V to 10V and provides a jumper-selectable output voltage of 0.9V, 1V, 1.2V, 1.5V, 1.8V or a user-defined value down to 200mV. The regulator optimizes stability and transient response with low ESR ceramic output capacitors as small as 10µF. Other LT3022 features include 0.05% typical line regulation and 0.05% typical load regulation. In shutdown, the quiescent current typically drops to 7.5µA. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis and reverse-current protection.
