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.
