General Description
The IFX2931 is a positive voltage regulator with a very low quiescent current of 1mA or less when supplying 10mA
loads. The IFX2931GV50 also offers an extremely low dropout voltage required for proper regulation: 0.2V for
output currents of 10mA. 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 100mA 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 comes in an 8-lead SMD package (PG-DSO-8).
