Key Features
- Fixed 3.3V output low-dropout regulator with only 0.25V typical dropout voltage at full load, enabling efficient power conversion from 3.9V to 5.5V input
- 1A continuous output current capability with fast transient response, ideal for powering DSPs, FPGAs, and microcontrollers in space-constrained designs
- Absolute maximum 6V input voltage rating with built-in current limiting and thermal shutdown protection for robust system-level reliability
- Lead-free and RoHS-compliant TO-263 package with enhanced thermal dissipation for industrial and consumer applications
Applications
The TPS75533KCG3 is well-suited for post-regulation in multi-rail power supply systems where a stable 3.3V output is required from a 5V bus. It is commonly used in embedded systems, portable instruments, and industrial control boards to power digital logic, memory modules, and communication interfaces. The device's low dropout performance also makes it effective in battery-powered designs where supply headroom is limited.

Frequently Asked Questions
What is the output voltage and current rating of the TPS75533KCG3?
The TPS75533KCG3 provides a fixed 3.3V output with a maximum continuous output current of 1A. Its nominal dropout voltage is just 0.25V, with a maximum of 0.5V, requiring as little as 3.9V on the input to maintain regulation.
What is the input voltage range for the TPS75533KCG3?
The device operates with an input voltage range of 3.9V minimum to 5.5V maximum, with an absolute maximum input voltage of 6V. This makes it ideal for 5V bus post-regulation in standard embedded and industrial systems.
What package does the TPS75533KCG3 come in and what are its thermal characteristics?
The TPS75533KCG3 is housed in an R-PSFM-T5 package (TO-263, 5-pin), which provides excellent thermal dissipation through its exposed tab. This enables operation at higher load currents in systems requiring compact surface-mount integration.
Is the TPS75533KCG3 RoHS compliant and what is its expected product lifecycle?
Yes, the TPS75533KCG3 is lead-free and fully RoHS compliant, as indicated by its Pbfree Code 'Yes' and JESD-609 Code 'e3'. Its YTEOL rating of 15 years indicates strong long-term availability for production procurement and industrial designs.
What are typical applications and alternatives for the TPS75533KCG3?
Typical applications include 3.3V power supply regulation in microcontroller boards, FPGA systems, communication modules, and industrial controllers. A common alternative is the TPS7533 series or LM1117-3.3 from Texas Instruments, both offering similar fixed 3.3V LDO output with comparable dropout and current ratings.
