That fixed 5 V output is the single non-negotiable spec: if your rail is 5 V, this is the exact ordering code. ## 2.25 MHz switching — small passives, tight layout The 2.25 MHz switching frequency lets you use a small inductor and low-value ceramic output capacitor — typically 1 µH and 10 µF — keeping the total solution footprint under 15 mm². No last-time-buy notice, no end-of-life window.","metaTitle":"TPS62173DSGT Step-Down Regulator, 5 V Fixed Output, 500 mA","metaDescription":"Texas Instruments TPS62173DSGT buck regulator: 3 V to 17 V input, 5 V fixed output, 500 mA, 2.25 MHz switching, 8-WSON package.
