The maximum allowable power dissipation at any ambient temperature is given: P D (max) = (TJ (max) - Tamb)/θJA, exceeding the maximum allowable power limit will result in excessive di e temperature; thus, the regulator will go into thermal shutdown. The junction to ambient thermal resistance θJA of different packages may be different, and the he value of θJA depends on mounting technique.

Pin No. Pin name I/O Functions FUNCTION DESCRIPTION The AMS1084 is a LDO regulator, its pass transistor is made up of a sing le NPN transistor being driven by a PNP. The dropout voltage is defined as: VDROP = VBE+ VSAT. The AMS084 has two versions: the fixed output version and the adjustable output version. Output voltages can be and overheating that would create excessive junction temperature. The adjustable output version requires a 22 μF or bigger tantalum capacitor at output for AMS1084 stabili ty. The capacitor for fixed output version can be smaller and should be determined base on actual application. Generally, the stability of linear regulator stability decreases with output currents increase.
