... 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, IRUH50PA23B1M requires the use of output capacitors as part of the device frequency compensation. The device requires a minimum of 220 stability. ...
