Product Summary

The TPS73733DCQR is a 1A low-dropout regulator with reverse current protection. Its applications include point of load regulation for DSPs, FPGAs, ASICs, and microprocessors, post-regulation for switching supplies, portable/battery-powered equipment. The TPS73733DCQR 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 20nA and ideal for portable applications. The TPS73733DCQR protected by thermal shutdown and Protection foldback current limit.
