Product Overview

The LT1529IQ#PBF is a low-dropout Regulator with micro-power quiescent current and shutdown. The device is capable of supplying 3A of output current with a dropout voltage of 0.6V. Designed for use in battery-powered systems, the low quiescent current, 50µA operating and 16µA in shutdown, makes it an ideal choice. The quiescent current is well controlled and it does not rise in dropout as it does with many other low-dropout PNP regulators. Other features of the LT1529 include the ability to operate with small output capacitors. It is stable with 22µF on the output while older devices require up to 100µF for stability. Small ceramic capacitors can be used, enhancing manufacturability. Also the input may be connected to voltages lower than the output voltage, including negative voltages, without reverse current flow from output to input. This makes the LT1529 ideal for backup power situations where the output is held high and the input is at ground or reversed.
