Low Dropout Linear Voltage Regulator IFX2931GV50 IFX2931GV33 Data Sheet Rev. 1.13, 2011-02-10 Standard Power Low Dropout Linear Voltage Regulator 1 Overview Features - Very Low Quiescent Current - Output Current in Excess of 100m A - Input-Output Differential Less than 0.6V for 5V-Version - Reverse Battery Protection - Output Current Limitation - Overtemperature Shutdown - Mirror-Image Insertion Protection - Needs only small Output Capacitor COUT = 10 µF - Green Product (Ro HS pliant) PG-DSO-8 For automotive and transportation applications, please refer to the Infineon TLE and TLF voltage regulator series. General Description The IFX2931 is a positive voltage regulator with a very low quiescent current of 1m A or less when supplying 10m A loads. The IFX2931GV50 also offers an extremely low dropout voltage required for proper regulation: 0.2V for output currents of 10m A. Therefore the IFX2931 is the ideal supply for standby power systems. It is suitable for e.g. memory standby circuits, CMOS and other low power processor power supplies. It certainly can also be used for any system demanding as much as 100m A of output current. The IFX2931 is protected from reverse polarity condition and can withstand input voltages of 28 V continously. The IFX2931 cannot be harmed by temporary mirror-image insertion. Additional protection Features such as output current limitation and overtemperature shutdown are also implemented. The IFX2931 es in an 8-lead SMD package (PG-DSO-8).
