Product Summary

The TPS73701DCQR is a Low-Dropout Regulator. The TPS73701DCQR uses an NMOS pass element in a voltage-follower configuration. This topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a small 1.0μF ceramic output capacitor. The NMOS topology also allows very low dropout for the die size used. The TPS73701DCQR uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is under 1mA and ideal for portable applications. These devices are protected by thermal shutdown and foldback current limit. The applications of the TPS73701DCQR include Point of Load Regulation for DSPs, FPGAs, ASICs, and Microprocessors, Post-Regulation for Switching Supplies and Portable/Battery-Powered Equipment.
