resistance JA, and the ambient temperature Tamb. The maximum allowable power dissipation at any ambient temperature is given: PD (max) = (TJ (max) - Tamb)/JA, 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 resistance JA of different packages may be different, and the he value of JA depends on mounting technique.

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 22 F 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. TYPICAL APPLICATION CIRCUIT Figure 1. Typical Fixed Output Voltage Figure 2.
