An adjustable option ranging (1.2-V to 5.5-V) from 1.22 V to 5.5 V is also available. The integrated • Input Voltage Down to 1.8 V supervisory circuitry provides an active low RESET • Low 170-mV Dropout Voltage at 1 A signal when the output falls out of regulation. The no (TPS72525) capacitor/any capacitor feature allows the customer to tailor output transient performance as needed. • Stable With Any Type/Value Output Capacitor Therefore, compared to other regulators capable of • Integrated Supervisor (SVS) With 50-ms providing the same output current, this family of RESET Delay Time regulators can provide a stand-alone power supply • Low 210-µA Ground Current at Full Load solution or a post regulator for a switch mode power supply. (TPS72525) • Less than 1-µA Standby Current These regulators are ideal for higher current appli- cations. The family operates over a wide range of • ±2% Output Voltage Tolerance Over Line, input voltages (1.8 V to 6 V) and has very low Load, and Temperature (-40 °C to 125°C) dropout (170 mV at 1-A). • Integrated UVLO Ground current is typically 210 µA at full load and • Thermal and Overcurrent Protection drops to less than 80 µA at no load. Standby current • 5-Lead SOT223-5 or DDPAK and 8-Pin SOP is less than 1 µA. (TPS72501 only) Surface Mount Package Each regulator option is available in either a SOT223-5, D (TPS72501 only), or DDPAK package. With a low input voltage and properly heatsinked • PCI Cards package, the regulator dissipates more power and • Modem Banks achieves higher efficiencies than similar regulators • Telecom Boards requiring 2.5 V or more minimum input voltage and higher quiescent currents. These features make it a • DSP, FPGA, and Microprocessor Power viable power supply solution for portable, bat- Supplies tery-powered equipment. • Portable, Battery-Powered Applications NOTE: TPS72501 replaces RESET with FB. Tab is GND for the DCK and KTT packages.
