What are the key features of TPS73633DBVT?
- Fixed 3.3V output with ultra-low 75mV (typical) dropout voltage at full load
- 400mA output current capability in a tiny SOT-23-5 (SOT23 5-Pin) footprint
- Wide input voltage range: 3.5V to 5.5V (6V absolute maximum)
- High power-supply rejection ratio (PSRR) for clean output in noise-sensitive designs
- RoHS-compliant, lead-free (Pb-free) construction with 15-year YTEOL support
What is TPS73633DBVT used for?
The TPS73633DBVT is widely used in portable consumer electronics, IoT sensor nodes, and wearable devices where a stable 3.3V rail must be derived from a single-cell Li-ion or 5V USB supply with minimal power loss. Its ultra-low dropout and high PSRR make it an excellent choice for RF front-ends, microcontroller VCC rails, and precision analog circuitry that demand low-noise regulation. The compact SOT-23-5 package also suits space-constrained designs such as USB dongles, Bluetooth modules, and handheld medical instruments.

Frequently Asked Questions
What is the output voltage and maximum output current of the TPS73633DBVT?
The TPS73633DBVT provides a fixed 3.3V output and supports up to 400mA of continuous output current. Its typical dropout voltage is only 75mV at full load, making it suitable for low-headroom battery-powered systems.
What input voltage range does the TPS73633DBVT support?
The device operates with an input voltage between 3.5V and 5.5V (absolute maximum 6V). This range makes it compatible with single-cell Li-ion batteries (3.6–4.2V) and standard 5V USB or regulated supply rails.
What package does the TPS73633DBVT use, and is it RoHS compliant?
The TPS73633DBVT comes in a 5-pin SOT-23 (SOT-23-5) surface-mount package, which measures approximately 2.9 × 1.6 mm. It is fully RoHS-compliant and lead-free (Pb-free code: Yes), with a rated 15-year end-of-life support period.
What are typical applications for the TPS73633DBVT?
This LDO regulator is commonly used to power microcontrollers, RF transceivers, Bluetooth and Wi-Fi modules, IoT sensor nodes, wearables, and precision analog circuits requiring a clean, stable 3.3V supply with low noise and minimal quiescent current.
