- Fixed 3.3 V output with only 250 mV typical dropout voltage, enabling efficient operation down to 3.55 V input
- Wide input voltage range of 3.9 V to 5.5 V (absolute max 6 V) suits single Li-ion or 5 V rail applications
- Compact 5-pin SOT-23 (R-PSSO-G5) package minimizes board space in space-constrained portable designs
Applications
The TPS75533KTTR is well-suited for powering microcontrollers, sensors, and low-power logic circuits in battery-operated handheld devices. Its low dropout voltage makes it ideal for 5 V to 3.3 V conversion in USB-powered accessories and IoT nodes. The small SOT-23 footprint also fits wearables and compact embedded modules requiring stable 3.3 V rails.

Frequently Asked Questions
What is the minimum input voltage required to maintain a regulated 3.3 V output on the TPS75533KTTR?
The TPS75533KTTR requires a minimum input voltage of approximately 3.55 V to sustain a 3.3 V regulated output, given its 250 mV typical dropout voltage. The specified operating input voltage range starts at 3.9 V, and the absolute maximum input is 6 V, making it compatible with 5 V or single Li-ion supply rails.
Which battery-powered IoT designs benefit most from using the TPS75533KTTR instead of a standard 3.3 V regulator?
IoT nodes running from a nearly depleted Li-ion cell (around 3.6 V to 3.7 V) benefit most, since the 250 mV dropout voltage allows the regulator to maintain a stable 3.3 V output at input voltages as low as 3.55 V. This extends usable battery life by 10–15% compared to regulators with 500 mV or higher dropout.
How does the 5-pin SOT-23 package of TPS75533KTTR compare to TO-252 for space-constrained PCB designs?
The 5-pin SOT-23 (R-PSSO-G5) package of TPS75533KTTR occupies roughly 3 mm × 3 mm of PCB area, significantly smaller than the TO-252 footprint at approximately 6.5 mm × 8 mm. For designs with less than 10 mm² available per regulator, the SOT-23 package is the preferred choice, and the KTTR suffix indicates tape-and-reel packaging for automated assembly.
