PACKAGE PACKING 5.0V TS2938CS50 RLG SOP-8 2,500pcs / 13” Reel 3.3V TS2938CS33 RLG SOP-8 2,500pcs / 13” Reel Note: 1. Compliant to RoHS Directive 2011/65/EU and in accordance to WEEE 2002/96/EC. 2. Halogen-free according to IEC 61249-2-21 definition. BLOCK DIAGRAM APPLICATION INFORMATION The TS2938 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 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. Output Capacitor The TS2938 series requires an output capacitor to maintain stability and improve transient response. Proper capacitor selection is important to ensure proper operation. The output capacitor selection is dependent upon the ESR of the output capacitor the maintain stability. When the output capacitor is 6.8µF or greater, the output capacitor should have an ESR less than 2ohm. This will improve transient response as well as promoted stability. Ultra low ESR capacitors (<100mohm), such as ceramic chip capacitors may promote instability. These very low ESR levels may cause an oscillation and/or under damped transient response. A low ESR solid tantalum capacitor works extremely well and provide good transient response and stability over temperature. Aluminum electrolytic can also be used, as long as the ESR of the capacitor is <2ohm. The value of the output capacitor can be increased without limit. Higher capacitance values help to improved transient response and ripple rejection and reduce output noise. |
