LD1985L18AF5R 3V3 LDO Regulator
Sku:
LD1985L18AF5R
- Very low drop out voltage (280mV at 150mA and 7mV at 1mA load)
- Very low quiescent current (2mA typ. at 150mA load and 80uA at no load)
- Output current up to 150mA
- Logic controlled electronic shutdown
- Internal current and thermal limit
- Low output noise voltage 30uVrms
The UTC LD1985 is a 150mA fixed output voltage regulator withultra 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 whenInhibit 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.
