Note1: The maximum allowable power dissipation is a function of maximum operating junction temperatureJ T

(max), the junction to ambient thermal resistanθcJeA, and the ambient temperatureamTb. The maximum

allowable power dissipation at any ambient temperature is given: PD (max) = (TJ (max) • Tamb)/θJA, exceeding the

maximum allowable power limit will result in excessive die temperature; thus, the regulator will go into thermal

shutdown. The junction to ambient thermal resistancθeJA of different packages may be different, and the he

value of θJA depends on mounting technique.

SA1117

FUNCTION DESCRIPTION

The SA1117 is a LDO regulator, its pass transistor is made up of a single NPN transistor being driven by aPNP.

The dropout voltage is defined as: VDROP = VBE+ VSAT.

The SA1117 has two versions: the fixed output version and the adjustable output version. Output voltages can be

1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V.On•chip thermal shut•down circuit provides protection against overload

and overheating that would create excessive junction temperature.

The adjustable output version requires a 22μF or bigger tantalum capacitor at output for SA1117 stability. 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.

circuit based on the real test.
