General Description
The TLF2931 is a positive voltage regulator with a very low quiescent current of 1mA or less when supplying
10 mA loads. The TLF2931GV50 provides an extremely low dropout voltage of less than 0.2 V for output currents
up to 10 mA. Therefore the TLF2931 is the ideal supply for standby power systems. It certainly can also be used
for any system demanding as much as 100 mA of output current. The AEC qualified device is designed to
withstand the harsh environment and operation conditions of automotive applications.
The TLF2931 is protected from reverse polarity condition and can withstand input voltages of 28 V continuously.
The TLF2931 cannot be harmed by temporary mirror-image insertion. Additional protection features such as
output current limitation and overtemperature shutdown are also implemented. The TLF2931 comes in an 8-lead
SMD package (PG-DSO-8).
