The TPS73HD3xx family of dual voltage regulators offers very low dropout voltages and dual outputs in acompact package. Designed primarily for DSP applicaTIons, these devices can be used in any mixed-outputvoltage applicaTIon with each regulator supporTIng up to 750 mA. Output current can be allocated as desiredbetween the two regulators and used to power many of todays DSPs. Low quiescent current and very lowdropout voltage assure maximum power usage in battery-powered applicaTIons. Texas Instruments PowerPADTSSOP package allows use of these devices with any voltage/current combination within the range of the listedspecifications without thermal problems, provided proper device mounting procedures are followed. Separateinputs allow the designer to configure the source power as desired. Dual active-low reset signals allow resettingof core-logic and I/O separately. Remote sense/feedback terminals provide regulation at the load. TheTPS73HD3xx are available in 28-pin PowerPAD TSSOP. They operate over a free-air temperature range of–40°C to 125°C.
