The adjustable output from 0.6 V to 5.5 V lets it feed 1.2 V core rails, 1.8 V I/O, or 3.3 V peripheral supplies from the same BOM line. Compared to the LMR33630APCQRNXRQ1 (3 A, 3.8 V–36 V input, 125 °C TJ), the TPS628502DRLR trades input range and output current for a smaller package and higher junction temperature. The LM53625LQURNLRQ1 (2.5 A fixed output, 150 °C TJ) is a closer thermal peer but has a fixed output voltage, so the adjustable TPS628502DRLR gives more design flexibility if your output voltage is non-standard. For volume RFQs, the base product number TPS628502 covers multiple output current and package variants; the DRLR suffix specifically identifies the SOT-583 package on 7-inch reel.","metaTitle":"TPS628502DRLR Texas Instruments 2A Step-Down Buck Regulator","metaDescription":"Active TPS628502DRLR from TI: 2A adjustable buck, 2.7V–6V input, 1.8–4 MHz switching, –40°C to 150°C junction.
