Key Features
- Fixed 3.3 V output with only 0.6 V typical dropout voltage, enabling operation from supplies as low as 3.9 V
- Wide input voltage range from 4 V to 65 V covering industrial, telecom, and automotive bus voltages
- Ultra-low quiescent current suitable for always-on monitoring circuits and battery-sensitive applications
Applications
TPS7A4433DGQR is well-suited for providing a stable 3.3 V bias rail in industrial control systems, PLC backplanes, and field instruments powered from 24 V or 48 V industrial buses. Its wide 4 V to 65 V input range also makes it effective in automotive infotainment and ADAS modules requiring a clean 3.3 V logic supply. The device is equally applicable in telecom line-cards and test equipment where a post-regulation stage must reject high-voltage supply noise.

Frequently Asked Questions
What is the maximum input voltage TPS7A4433DGQR can handle in industrial 48 V bus applications?
TPS7A4433DGQR supports a maximum input voltage of 65 V, making it suitable for 48 V nominal industrial bus systems that can surge beyond 60 V. The absolute maximum is 85 V for transient protection, giving designers robust margin in harsh industrial environments.
How much dropout voltage does TPS7A4433DGQR exhibit at full 50 mA load?
At maximum output current of 50 mA, TPS7A4433DGQR exhibits a typical dropout voltage of 0.6 V and a worst-case dropout voltage of 0.8 V. This means a minimum input of approximately 3.9 V is sufficient to maintain the 3.3 V regulated output without dropout.
Which compact package does TPS7A4433DGQR use and how does the thermal pad help dissipation?
TPS7A4433DGQR is housed in a 10-pin MSOP-PowerPAD (S-PDSO-G10) package. The exposed thermal pad on the bottom of the package conducts heat directly to the PCB copper pour, reducing junction temperature by several degrees Celsius even at 50 mA output current and enabling operation across the full industrial temperature range.
Is TPS7A4433DGQR RoHS compliant and lead-free for green manufacturing?
Yes, TPS7A4433DGQR is fully RoHS compliant and lead-free as indicated by its e4 JESD-609 code and Pbfree designation. This makes it compatible with SAC solder alloys and suitable for green manufacturing processes across consumer, industrial, and automotive supply chains.
