TLF2931 Low Dropout Linear Voltage Regulator TLF2931GV50 TLF2931GV33 Data Sheet Rev. 1.0, 2010-10-06 Automotive Power Low Dropout Linear Voltage Regulator 1 TLF2931 Overview Features • • • • • • • • • • Very low Quiescent Current Output Current in Excess of 100mA 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 (RoHS compliant) AEC Qualified PG-DSO-8 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).
