The 3 V to 17 V input range covers common 5 V, 12 V, or unregulated intermediate buses. The 2.25 MHz switching frequency lets the layout engineer use small inductors and capacitors — typically 2.2 µH and 10 µF — shrinking the PCB footprint.","metaTitle":"TPS62171DSGR Texas Instruments Buck Regulator 1.8V 500mA","metaDescription":"TPS62171DSGR from Texas Instruments: step-down buck converter, fixed 1.8V output, 500mA, 2.25MHz switching, -40°C to 85°C, 8-WSON package.

However, the LM53625LQURNLRQ1 is an automotive AEC-Q100 part rated to 150°C junction and delivers 2.5 A output — a higher current and temperature grade than the TPS62171DSGR.
