Application Information

The TS39101/2/4 are high performance with low dropout voltage regulator suitable for moderate to high current and

voltage regulator application. Its 630mV dropout voltage at full load and over temperature makes it especially valuable

in battery power systems and as high efficiency noise filters in post regulator applications. Unlike normal NPN

transistor design, where the base to emitter voltage drop and collector to emitter saturation voltage limit the minimum

The TS39101/2/4 s fully protected from damage due to fault conditions. Linear current limiting is provided. Output

current during overload conditions is constant. Thermal shutdown the device when the die temperature exceeds the

maximum safe operating temperature. Transient protection allows device survival even when the input voltage spikes

above and below nominal. The output structure of these regulators allows voltages in excess of the desired output

voltage to be applied without reverse current flow.
