The IFX1763 ADJ 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.
