Fixed 1.2 V rail for point-of-load regulation
Input range and load ceiling
The 2.5 V minimum input means this part cannot regulate from a single Li-ion cell near its 3.0 V cutoff — it needs a pre-regulated 3.3 V or 5 V bus. The 600 mA output ceiling suits low-power MCU cores, sensor rails, or RF front-end supplies. Compared to the LM53625LQURNLRQ1 (2.5 A, 2.1 MHz, automotive grade), the TPS62003DGSR is a lighter-duty industrial alternative with a lower switching frequency that reduces switching losses at light loads.
It does not reach the 125°C or 150°C junction temperatures of automotive-grade peers like the LM53625LQURNLRQ1 or LMR33630APCQRNXRQ1.
