Key Features
- Dual 1.8 V and 3.3 V fixed outputs in a single package simplifies power supply design for dual-rail digital systems, reducing BOM and PCB area
- 750 mA output current per channel supports power-hungry FPGAs, DSPs, and processor core and I/O rail requirements simultaneously
- Low 220 mV typical dropout voltage maximizes efficiency and extends operating range closer to the output voltage
- 0.065% maximum load regulation ensures stable output under dynamic load transients in high-performance digital applications
Applications
The TPS73HD318PWPG4 is designed for FPGAs, ASICs, and multi-core DSPs that require separate 1.8 V core and 3.3 V I/O supply rails from a single regulator device. Its dual-output architecture is also well suited for communication modules, network switches, and industrial control boards where two standard logic supply voltages must be generated efficiently from a 5 V or 9 V input. The HTSSOP package and low dropout make it a compact, thermally efficient solution for telecom line cards and embedded computing platforms.

Frequently Asked Questions
What output voltages does the TPS73HD318PWPG4 provide?
The TPS73HD318PWPG4 provides two fixed output voltages: 1.8 V and 3.3 V. Both outputs are independently regulated and can supply up to 750 mA each, making the device ideal for powering FPGA core and I/O rails, processor core and peripheral supplies, or any dual-rail digital system from a single regulator IC.
What is the dropout voltage of the TPS73HD318PWPG4?
The TPS73HD318PWPG4 has a typical dropout voltage of 220 mV. This low dropout characteristic means the input supply needs to be only 220 mV above the output rail under nominal conditions, maximizing efficiency and allowing operation over a wider input voltage range down to the 3.97 V minimum input.
What is the input voltage range for the TPS73HD318PWPG4?
The device accepts input voltages from 3.97 V minimum to 10 V maximum, with an absolute maximum rating of 11 V. This range is compatible with regulated 5 V rails as well as 9 V unregulated adapter outputs, providing flexibility in multi-supply system architectures.
What package does the TPS73HD318PWPG4 use?
The TPS73HD318PWPG4 is housed in a 28-pin HTSSOP (Heat-sink Thin Shrink Small Outline Package, JESD-30 code R-PDSO-G28). The exposed thermal pad on the underside of the HTSSOP enhances heat dissipation, supporting higher output currents without exceeding thermal limits in demanding applications.
Is the TPS73HD318PWPG4 RoHS compliant and what are its typical applications?
Yes, the G4 suffix and JESD-609 code e4 confirm full RoHS compliance and lead-free construction. Typical applications include FPGA and ASIC power supplies, industrial computing boards, network equipment line cards, and embedded systems requiring stable dual-rail LDO regulation with minimal external components.
