Frequently Asked Questions
What is the output voltage and current rating of TPS78633KTTRE3?
The TPS78633KTTRE3 is a fixed 3.3V output LDO regulator with a maximum output current of 150mA. It maintains ±2% output voltage accuracy over the full operating temperature and load range, making it suitable for precision low-power applications.
What is the input voltage range for TPS78633KTTRE3?
TPS78633KTTRE3 supports an input voltage range from 2.7V to 10V, allowing it to be powered by a single-cell Li-ion battery, a 2-cell NiMH pack, or regulated 5V/9V supplies. The wide range gives designers flexibility across different power architectures.
How low is the quiescent current of TPS78633KTTRE3, and why does it matter?
The TPS78633KTTRE3 has a typical quiescent current of only 30µA, which is critical for battery-operated devices that spend most of their time in sleep or standby mode. This ultra-low IQ helps extend battery life significantly compared to standard LDO regulators.
What package is TPS78633KTTRE3 available in?
TPS78633KTTRE3 is available in a 5-pin SOT-23 (KTT) package. The 'RE3' suffix indicates it is RoHS-compliant and uses a tape-and-reel packaging format, making it suitable for automated SMT assembly in high-volume production.
What are typical applications for TPS78633KTTRE3?
Typical applications include IoT sensor nodes, wearable electronics, handheld medical devices, wireless modules, and portable consumer electronics. Any design requiring a stable 3.3V rail with minimal standby power draw benefits from this ultra-low-dropout regulator.
