- AEC Qualified 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 outp ut current. The AEC qualif ied device is designed to withstand the harsh environment and operation conditions of automotive applications. The TLF2931 is protected from reverse polarity conditio n and can withstand input voltages of 28 V continuously. The TLF2931 cannot be harmed by temporary mirror-image insertion. Additional prot ection features such as output current limitation and overtemperature shutdown are also implemented. The TLF2931 comes in an 8-lead SMD package (PG-DSO-8).

4.1 Absolute Maximum Ratings
Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not designed for continuous repetitive operation.
4.2 Functional Range
Note: Within the functional range the IC operates as described in the circuit description. The electrical characteristics are specified within the conditions given in the related electrical characteristics table.
