Low Dropout Linear Voltage Regulator IFX1763XEJV/LDV
Application Circuit: Short-circuit protection

The IFX1763XEJV/LDV is a low noise micropower LDO. The device is capable
of supplying an output current of 500mA with a dropout voltage of 320mV.

Its low quiescent current of 30µA makes the device also an excellent choice for
being used in battery-powered systems.

By means of an external bypass capacitor a very low noise level of the output voltage
can be achieved. At the same time the usage of such a bypass capacitor allows
to increase the reaction time leading to obtain faster transient response in case of load
steps as well as to modify the start-up behavior (soft start) when supply voltage is
ramped up rapidly.

The bypass capacitors can be used from none up to a maximum of 10nF within the
stability range of the regulator.
