Linear Technology LT1521-3

the LT1521/LT1521-3/LT1521-3.3/ LT1521-5 include the ability to operate with very small output capacitors. They are stable with only 1.5µF on the output while most older devices require between 10µF and 100µF for stability. This makes the LT1521 series ideal for backup power situations where the output is held high and the input is low or reversed.

DESCRIPTION

The LT ®1521/LT1521-3/LT1521-3.3/LT1521-5 are low dropout regulators with micropower quiescent current and shutdown. These devices are capable of supplying 300mA of output current with a dropout voltage of 0.5V. Designed for use in battery-powered systems, the low quiescent current, 12 µA operating and 6 µA in shutdown, makes them an ideal choice. The quiescent current is well controlled; it does not rise in dropout as it does with many other low dropout PNP regulators. Other features of 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. Under these conditions only 5µA will flow from the output pin to ground. , LTC and LT are registered trademarks of Linear Technology Corporation.
