User-programmable soft-start minimizes • 1% Accuracy Over Line, Load, and Temperature stress on the input power source by reducing capacitive inrush current on start-up. The soft-start is • Supports Input Voltages as Low as 0.8 V With monotonic and well suited for powering many External Bias Supply different types of processors and ASICs. The enable • Adjustable Output (0.8 V to 3.6 V) input and power-good output allow easy sequencing • Ultra-Low Dropout: 55 mV at 1.5 A (Typical) with external regulators. This complete flexibility permits the user to configure a solution that meets • Stable With Any or No Output Capacitor the sequencing requirements of FPGAs, DSPs, and • Excellent Transient Response other applications with special start-up requirements. • Available in 5-mm × 5-mm × 1-mm VQFN and A precision reference and error amplifier deliver 1% DDPAK/TO-263-7 Packages accuracy over load, line, temperature, and process. • Open-Drain Power-Good (5 × 5 VQFN) Each LDO is stable with low-cost ceramic output • Active High Enable capacitors, and the family is fully specified from –40°C to 125°C. The TPS742 devices are offered in a small (5 mm × 5 mm) VQFN package, yielding a 2 Applications highly compact total solution size. For applications • FPGA Applications that require additional power dissipation, the • DSP Core and I/O Voltages DDPAK/TO-263 (KTW) package is also available. • Servers Device Information(1) • Post-Regulation Applications PART PACKAGE BODY SIZE (NOM) • Applications With Special Start-Up Time or NUMBER Sequencing Requirements VQFN (20) 5.00 mm × 5.00 mm TPS74201 DDPAK/TO-263 (7) 8.89 mm × 10.10 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
