... The IRU1502-33 provides Over Current Protection when the output current exceeds typically 1.4A. The output decreases to limit the power dissipation. Stability The IRU1502-33 requires the use of an output capacitor as part of the frequency compensation in order to make the regulator stable. A minimum input capacitance of 4.7mF and a minimum output capacitance 4.7mF Ce- ramic capacitor is needed for regulator stage as well as the specified minimum loads to guarantee stability ...

... PCB board design. From the datasheet, this thermal junction-to-ambient re- sistance is given as: =428C/W JA Where: 2.38C JC 18C CH 38.78C HA For IRU1502-33, the thermal design needs to be con- sider so that the resultant junction temperature is lower than the maximum operating temperature, which is 1258C. Therefore 1258C ...
