What are the key features of TPS75533KTTRG3?
- Ultra-low 250mV typical dropout voltage (500mV max) enabling efficient regulation from near-rail input sources down to 3.899V
- Fixed 3.3V output with 5.5V maximum input, covering USB, Li-Ion battery, and 5V rail power supply applications
- Compact 5-pin SOT-23 (R-PSSO-G5) package for space-efficient power management on dense PCBs
What is TPS75533KTTRG3 used for?
The TPS75533KTTRG3 is ideal for powering 3.3V digital logic, microcontrollers, and FPGAs from 5V or single Li-Ion battery rails in portable and embedded systems. Its low dropout voltage of 250mV allows operation even when the input supply sags close to the 3.3V output during battery discharge. The device suits USB-powered accessories, industrial sensors, and IoT nodes requiring a stable low-noise supply.

Frequently Asked Questions
What is the minimum input voltage the TPS75533KTTRG3 requires to maintain its 3.3V regulated output?
The TPS75533KTTRG3 requires a minimum input voltage of 3.899V to maintain the regulated 3.3V output, given its typical dropout voltage of 250mV (500mV max). This low dropout allows the device to keep regulating even during battery discharge on single Li-Ion or 3xAA alkaline battery packs.
How does the TPS75533KTTRG3 perform in USB-powered 3.3V supply circuits?
In USB-powered designs, the TPS75533KTTRG3 accepts the 5V USB rail (within its 3.899V–5.5V input range) and delivers a stable 3.3V output. The 250mV dropout headroom comfortably handles USB voltage sag under load, and the fixed-output configuration eliminates the resistor divider network required by adjustable LDOs.
What is the SOT-23 package outline for the TPS75533KTTRG3 and why does it matter for board layout?
The TPS75533KTTRG3 uses a 5-pin SOT-23 surface-mount package (JESD-30 code R-PSSO-G5) measuring approximately 2.9mm x 1.6mm. This tiny footprint is well suited for board areas adjacent to processor or FPGA I/O banks where space is at a premium, and it requires only two small external capacitors to stabilize the LDO output.
Is the TPS75533KTTRG3 compliant with RoHS and lead-free requirements?
The TPS75533KTTRG3 carries JESD-609 Code e3, confirming a lead-free, RoHS-compliant package finish. It is also marked Pb-free, satisfying EU RoHS Directive and China RoHS 2.0 environmental requirements for products sold in regulated markets worldwide.
