Frequently Asked Questions
What is the output voltage and current rating of the TPS75825KTTR?
The TPS75825KTTR provides a fixed 2.5V output with a maximum output current of 1A. The typical dropout voltage at full load is 150mV, and the maximum dropout is 300mV, enabling operation with input voltages as low as 3.5V while maintaining regulation.
What package does the TPS75825KTTR use?
The TPS75825KTTR uses a 5-pin SOT-223 surface-mount package (JESD-30 code R-PSSO-G5) with a tape-and-reel (KTTR suffix) packaging format. The SOT-223 package includes a large exposed pad for improved thermal dissipation, supporting up to 1A continuous output current.
Is the TPS75825KTTR suitable for battery-powered designs?
Yes, the TPS75825KTTR is well-suited for battery-powered applications. With a 3.5V minimum input voltage and only 150mV typical dropout at 1A, it can operate from a single-cell Li-ion battery down to near-depleted states. Its low quiescent current further extends battery runtime in portable designs.
What is the input voltage range of the TPS75825KTTR?
The TPS75825KTTR accepts an input voltage range from 3.5V minimum to 5.5V maximum, with an absolute maximum rating of 6V. This range is compatible with 5V USB power rails, 4-cell NiMH battery packs, and single-cell Li-ion batteries in portable and industrial applications.
What are common alternatives to the TPS75825KTTR?
Close alternatives include the TPS7A2525PDBVR (2.5V, 300mA in SOT-23), the TLV1117-25 (2.5V, 800mA LDO), and the LP2985-25DBVR for lower-current applications. For a drop-in 1A replacement in SOT-223, the TPS75825Q (automotive-grade) is available for higher-reliability environments.
