    Description

    The TPS725xx family of 1-A low-dropout (LDO) linear regulators has fixed voltage options available that are commonly used to power the latest DSPs, FPGAs, and microcontrollers. An adjustable option ranging from 1.22 V to 5.5 V is also available. The integrated supervisory circuitry provides an active low RESET\ signal when the output falls out of regulation. The no capacitor/any capacitor feature 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 are ideal for higher current 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 is typically 210 µA at full load and drops to less than 80 µA at no load. Standby current is less than 1 µA.

    Each regulator option is available in either a SOT223-5, D (TPS72501 only), 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 it 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-µF output capacitor.

    Unlike some regulators that have a minimum current requirement, the TPS725 family 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 it ideal for telecom boards, modem banks, and other noise sensitive applications.
