(1) 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 integrated supervisory circuitry provides an active ow RESET signal when the output falls out of regulation. The no capacitor/any capacitor feature of TPS72616 allows the customer to tailor output transient performance as needed. Therefore,compared to other regulators capable of providing the same output current, this family of regulators can provide a stand alone power supply solution or a post regulator for a switch mode power supply.
These regulators TPS72616 are ideal for higher curret applications.The family operates over a wide range of input voltages (1.8 V to 6 V) and has very low dropout (170 mV at 1-A).
Ground current of TPS72616 is typically 210 A at full load and drops to less than 80 A at no load. Standby current is less than 1 A.
Each regulator option of TPS72616 is available in either a SOT223-5 or DDPAK package. With a low input voltage and properly heatsinked package, the regulator dissipates more power and achieves higher efficiencies than similar regulators requiring 2.5 V or more minimum input voltage and higher quiescent currents. These features make TPS72616 a viable power supply solution for portable, battery powered equipment
Although an output capacitor is not required for stability, transient response and output noise are improved with a 10-F output capacitor. Unlike some regulators that have a minimum current requirement, the TPS72616 is stable with no output load current. The low noise capability of this family, coupled with its high current operation and ease of power dissipation, make TPS72616 ideal for telecom boards, modem banks, and other noise sensitive applications.
