† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The TPS73HD318_1133757 family of dual voltage regulators offers very low dropout voltages and dual outputs in a compact package. Designed primarily for DSP applications, these devices can be used in any mixed-output voltage application with each regulator supporting up to 750 mA. Output current can be allocated as desired between the two regulators and used to power many of todays DSPs. Low quiescent current and very low dropout voltage assure maximum power usage in battery-powered applications. Texas Instruments PowerPAD TSSOP package of TPS73HD318_1133757 allows use of these devices with any voltage/current combination within the range of the listed specifications without thermal problems, provided proper device mounting procedures are followed. Separate inputs of TPS73HD318_1133757 allow the designer to configure the source power as desired. Dual active-low reset signals allow resetting of core-logic and I/O separately. Remote sense/feedback terminals provide regulation at the load. The  TPS73HD318_1133757 are available in 28-pin PowerPAD TSSOP. They operate over a free-air temperature range of 40 to 125
