100mA LDO’s Low Quiescent Current Ideal in Battery-Powered Applications
ON Semiconductor’s NCP711 is a series of Low Dropout (LDO) regulators which are suitable for use in battery-powered, always-on applications because of their very low quiescent current and ability to handle a wide range of input voltages.
The NCP711, a CMOS LDO, is rated for a constant output current of up to 100mA from an input voltage ranging between 2.7V and 18V. The NCP711 is available in versions with a fixed output voltage of 3.0V, 3.3V or 5.0V, or with an adjustable output voltage of between 1.2V and 17V.
The NCP711 is ideal for use in regulating the input from a lithium-ion battery pack containing up to nine cells in series, to supply a load such as a microcontroller or analog circuit.
The NCP711A LDOs are supplied in a five-lead SOT-23 package. The NCP711B LDOs in a six-lead DFN package include a Power Good circuit which indicates that the output voltage is in regulation. This signal may be used for power sequencing, or for resetting a microcontroller.
All NCP711 regulators include internal short-circuit and over-temperature protection functions.
