Description

General part information

LT3033 Series

The LT3033 is a very low dropout voltage (VLDO™) linear regulator that operates from a single input supply down to 0.95V. The device supplies 3A output current with 95mV typical dropout voltage. The LT3033 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to a switching regulator.The LT3033 optimizes stability and transient response with low ESR ceramic output capacitors as small as 10μF. Other features include programmable current limit, an output current monitor and a power good flag to indicate output voltage regulation. In shutdown, quiescent current typically drops to 22μA. Internal protection circuitry includes reverse-battery protection, current limiting with foldback, thermal limiting with hysteresis and reverse-current protection.The LT3033 is available as an adjustable device with an output voltage down to the 200mV reference. The device is available in a thermally enhanced, low profile 3mm × 4mm × 0.75mm QFN package.APPLICATIONSHigh Efficiency Linear RegulatorsBattery-Powered SystemsLogic SuppliesPost Regulator for Switching SuppliesWireless ModemsFPGA Core Supplies
