Full description

The UTC LD1985 is a 150mA fixed output voltage regulator with ultra low drop voltage and the low quiescent current.

It is specially designed for low noise, low power, battery applications such as mobile phones, palmtops, laptop computers, PDAs, DSC etc.

The quiescent current in sleep mode is less than 1uA when Inhibit pin is pulled low.

When the device is used as a local regulator, it is possible to put part of the board into standby mode by using the Shutdown Logic pin (TTL compatible) thereby decreasing the total power consumption.

With the correct choice of byepass capacitor the output noise can be reduced to 30uVrms.The UTC LD1985 is a 150mA fixed output voltage regulator with ultra low drop voltage and the low quiescent current.
