... Care should be taken to ensure that the input to the regulator is sufficiently free of noise and disturbances. Output Capacitance Like most ultra low dropout voltage regulators, IRUH33P253A1M requires the use of an output capacitor as part of the device frequency compensation. The device requires a minimum of 220µF tantalum to ensure stability. ...
