What are the key features of TPS77516PWPG4?
- Fixed 1.6 V regulated output with tight 2% accuracy for reliable digital core supply rails
- 500-mA output current with 1 V maximum dropout voltage supporting 2.7 V to 10 V input range
- 20-pin HTSSOP package with exposed thermal pad enables efficient heat dissipation in high-current designs
What is TPS77516PWPG4 used for?
TPS77516PWPG4 is well-suited for powering DSP and FPGA core voltage rails, digital baseband processors, and other logic circuits requiring a stable 1.6 V supply. Its 500-mA current capacity and wide 2.7 V to 10 V input range allow it to be fed from a variety of upstream regulators or battery voltages. The HTSSOP package with thermal pad is an advantage in designs where PCB-level heat dissipation is needed without adding a separate heatsink.

Frequently Asked Questions
What are the input voltage limits and output current rating of TPS77516PWPG4?
TPS77516PWPG4 accepts an input voltage from 2.7 V minimum up to 10 V maximum, and can supply up to 500 mA of output current at a fixed 1.6 V output. The maximum dropout voltage is 1 V, which means the input must exceed 2.6 V to maintain full regulation under heavy load.
How accurate is the output voltage of TPS77516PWPG4, and does that make it suitable for FPGA core power?
The device provides a fixed 1.6 V output with a 2% accuracy tolerance, which falls within the typical plus or minus 5% tolerance allowed by most FPGA core supply specifications. With 500 mA available, TPS77516PWPG4 can directly supply mid-range FPGA core rails such as those required by Xilinx Spartan-6 or similar devices in low-power configurations.
What line regulation performance does TPS77516PWPG4 deliver across its full input range?
TPS77516PWPG4 achieves a maximum line regulation of approximately 0.001168%, meaning the 1.6 V output shifts by less than 0.02 mV per volt of input change across the full 2.7 V to 10 V operating range. This excellent line regulation makes the device suitable for precision analog and mixed-signal circuits sensitive to power supply noise.
What thermal advantages does the 20-pin HTSSOP package of TPS77516PWPG4 offer compared with a standard TSSOP?
The HTSSOP package includes an exposed thermal pad on the underside that can be soldered directly to the PCB copper plane, dramatically reducing junction-to-board thermal resistance. At 500 mA and a 10 V input, TPS77516PWPG4 can dissipate up to 4.2 W theoretically, and the thermal pad is essential for keeping junction temperature within the safe operating range without requiring an external heatsink.
