The TPS62081DSGT is a fixed 1.8V output, 1.2A synchronous buck converter from TI's DCS-Control™ family, switching at 2 MHz.
Input voltage spans 2.3V to 6V, so a 5V rail is comfortably inside the window with margin.
Yes, the TPS62081DSGT is ROHS3 compliant.
The peer LM53625LQURNLRQ1 is an automotive-grade (AEC-Q100) 2.5A buck with a similar 2.1 MHz switching frequency, but it operates up to 150°C junction and requires a 3.9V minimum input. The LMR33630APCQRNXRQ1 is another automotive-grade 3A adjustable-output buck with 2.1 MHz switching and a wider 3.8V to 36V input range. Neither is a direct drop-in — the TPS62081DSGT is a non-automotive fixed-output part in a smaller 8-WSON package.
