Key Features
- Ultra-low 0.22V nominal dropout voltage with 0.325V maximum ensures efficient regulation even with marginal input-output differentials
- Fixed 3.3V output with 4.3V to 5.5V input range optimized for direct regulation from standard 5V power rails
- 5-pin TO-263 surface-mount power package provides excellent thermal dissipation for moderate to high current LDO applications
Applications
The TPS79633KTTR is well-suited for powering precision analog circuits, RF transceivers, and DSP cores requiring a clean, stable 3.3V supply derived from a 5V system rail. Its low dropout voltage ensures continued regulation as input voltage drops near the output level, making it ideal for battery-powered devices and USB-powered systems. The device also serves as a post-regulator after switching converters to reduce output ripple and supply noise-sensitive components such as ADCs and PLLs.

Frequently Asked Questions
What is the dropout voltage of the TPS79633KTTR?
The TPS79633KTTR features a nominal dropout voltage of 0.22V and a maximum dropout voltage of 0.325V, which means it can maintain regulation with input voltage as low as approximately 3.5V for a 3.3V output. This low dropout characteristic is particularly valuable in battery-powered applications where the supply voltage declines during discharge.
What is the input voltage range of the TPS79633KTTR?
The TPS79633KTTR accepts an input voltage from 4.3V minimum to 5.5V maximum, with an absolute maximum rating of 6V. This range is optimized for operation from a 5V regulated supply, making the device suitable for 5V bus-powered designs targeting 3.3V output rails in microcontroller, sensor, and mixed-signal systems.
What package does the TPS79633KTTR use and how does it help with thermal performance?
The TPS79633KTTR uses a 5-pin TO-263 (D2PAK) surface-mount package, JESD-30 code R-PSSO-G5. This power package features a large exposed metal tab that can be soldered to a PCB copper pour for efficient heat dissipation, enabling higher output current capability compared to smaller LDO packages in the same operating conditions.
Is the TPS79633KTTR RoHS compliant?
Yes, the TPS79633KTTR carries a Pb-free code of Yes and a JESD-609 code of e3, confirming it is manufactured without lead and meets RoHS environmental compliance requirements. This makes it suitable for designs targeting EU, China, and other regional environmental regulations governing hazardous materials in electronic equipment.
