What is TPS70245PWPG4 used for?
The TPS70245PWPG4 is ideal for powering dual-rail digital subsystems such as FPGA core and I/O voltage supplies, DSP processors, and mixed-signal boards that require both 1.2 V and 3.3 V simultaneously from a single 5 V or 3.6 V+ input. It is also used in portable industrial instruments and communication modules where low-noise LDO regulation from a compact package reduces BOM complexity.

Frequently Asked Questions
What output voltages and current ratings does TPS70245PWPG4 deliver simultaneously?
TPS70245PWPG4 provides two simultaneous fixed outputs: 1.2 V at up to 500 mA and 3.3 V at up to 250 mA, making it a compact dual-rail solution for mixed-voltage boards that need both a low-core logic supply and a standard I/O voltage from one regulator.
How low is the dropout voltage of TPS70245PWPG4 and what minimum input voltage is required?
The TPS70245PWPG4 has a typical dropout voltage of 170 mV with a maximum of 275 mV; the specified minimum input voltage is 3.641 V, so a 3.8 V to 6 V input comfortably covers both outputs with sufficient headroom across temperature and load conditions.
In what design scenarios does TPS70245PWPG4 reduce BOM count compared to using two separate LDO ICs?
Any design needing both 1.2 V core and 3.3 V I/O rails — such as FPGAs, ARM microcontrollers, or Ethernet PHYs — benefits from TPS70245PWPG4's dual output in a single 20-pin HTSSOP footprint, cutting PCB area, component count, and procurement complexity versus two discrete LDOs.
Does the exposed thermal pad on the HTSSOP package help manage power dissipation in high-current scenarios?
Yes, the 20-pin HTSSOP exposed pad (EP) on TPS70245PWPG4 allows direct solder attachment to a PCB copper pour, significantly reducing junction-to-board thermal resistance and enabling the device to sustain its full 500 mA output without overheating at elevated ambient temperatures up to 85°C.
