The LT3020IDD is a very low dropout voltage (VLDO™) linear regulator that operates from input supplies down to 0.9V. This device supplies 100mA of output current with a typical dropout voltage of 150mV. The LT3020IDD is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to that of a switching regulator.
The LT3020IDD regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 2.2µF. Other LT3020IDD features include 0% typical line regulation and 0.2% typical load regulation. In shutdown, quiescent current drops to 3µA.
Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis, and reverse-current protection. The LT3020IDD 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 LT3020IDD regulator is available in the low profile (0.75mm) 8-lead (3mm × 3mm) DFN package with exposed pad and the 8-lead MSOP package.
