The TS2938/A series is a high performance with low dropout voltage regulator suitable for moderate to high current and voltage regulator application. Its 500Mv (typ) 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 dropout voltage, dropout performance of the PNP output of these devices is limited only by low Vce saturation voltage.
The TS2938/A series is 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.

The TS2938/A series of fixed-voltage monolithic micro-power voltage regulators is designed for a wide range of applications. This device excellent choice of use in battery-power application. Furthermore, the quiescent current increases on slightly at dropout, which prolongs battery life.
This series of fixed-voltage regulators features very low ground current (100uA Typ.), very low drop output voltage (Typ. 60mV at light load and 600mV at 500mA) and output inhibit control. This includes a tight initial tolerance of 1% (TS2938A) and 2% (TS2938), extremely good line regulation of 0.05% typ., and very low output temperature coefficient. This series is offered in 5-pin of TO-252-5L and 8-pin SOP-8 package.
