Frequently Asked Questions
What is the dropout voltage of TC1300R-3.3VUA at full 300 mA load, and what minimum input voltage does this require?
TC1300R-3.3VUA has a maximum dropout voltage of 390 mV at 300 mA. To maintain a regulated 3.3 V output under worst-case conditions, the input must be at least 3.69 V. In practice the typical dropout is 210 mV, requiring only 3.51 V input, though the specified minimum input of 4.3 V ensures full rated-current operation across all tolerance conditions.
How does TC1300R-3.3VUA perform in a USB-powered device drawing up to 300 mA from a 5 V rail?
TC1300R-3.3VUA is well-matched to 5 V USB power applications. With a 5 V input and a 3.3 V output at 300 mA, the power dissipated in the LDO is approximately 510 mW. The MSOP-8 package has limited thermal resistance, so designs should verify junction temperature stays below the rated limit by estimating theta-JA for the chosen PCB copper area.
Can TC1300R-3.3VUA replace a larger SOT-223 LDO when upgrading a board layout to save space?
TC1300R-3.3VUA is housed in an MSOP-8 package, which at approximately 3 mm × 3 mm is smaller than a SOT-223 body of roughly 6.5 mm × 3.5 mm. Switching to TC1300R-3.3VUA can reduce the regulator footprint by more than 50%, though the SOT-223 tab provides better thermal dissipation for currents above 300 mA, so the swap is suitable only within TC1300R's 300 mA current budget.
What are the RoHS and Pb-free compliance details for TC1300R-3.3VUA when qualifying a lead-free product BOM?
TC1300R-3.3VUA carries a Pb-free code confirming lead-free solder finish, and the JEDEC e3 finish designation aligns with J-STD-020 classification for lead-free reflow. The plastic MSOP-8 body meets RoHS restricted substance requirements, making the part straightforward to include in CE-marked and RoHS-compliant product documentation without additional exemption filings.
