description

The TPS73HD3xx family of dual voltage regulators offers very low dropout voltages and dual outputs in a

compact package. Designed primarily for DSP applications, these devices can be used in any mixed-output

voltage application with each regulator supporting up to 750 mA. Output current can be allocated as desired

between the two regulators and used to power many of todays DSPs. Low quiescent current and very low

dropout voltage assure maximum power usage in battery-powered applications. Texas Instruments PowerPAD

TSSOP package allows use of these devices with any voltage/current combination within the range of the listed

specifications without thermal problems, provided proper device mounting procedures are followed. Separate

inputs allow the designer to configure the source power as desired. Dual active-low reset signals allow resetting

of core-logic and I/O separately. Remote sense/feedback terminals provide regulation at the load. The

TPS73HD3xx are available in 28-pin PowerPAD TSSOP. They operate over a free-air temperature range of

−40°C to 125°C.
