Frequently Asked Questions
What is the output voltage and accuracy of the TPS76733QPWP?
The TPS76733QPWP provides a fixed 3.3V output with ±2% accuracy, ensuring the output stays between approximately 3.234V and 3.366V across line, load, and temperature variations—suitable for powering precision digital and analog circuits.
What is the dropout voltage of the TPS76733QPWP at full load?
At a 1A full-load output current, the TPS76733QPWP has a typical dropout voltage of 230mV and a maximum of 575mV, allowing it to regulate down to a very small difference between input and output—ideal for low-headroom power supply designs.
What input voltage range does the TPS76733QPWP support?
The device operates with an input voltage from 3.875V to 10V, with an absolute maximum rating of 13.5V. This makes it compatible with 5V logic rails, single-cell Li-Ion batteries (when boosted), and automotive 12V systems with appropriate filtering.
Is the TPS76733QPWP suitable for automotive applications?
Yes. The 'Q' suffix in TPS76733QPWP indicates it is qualified for automotive use, meeting AEC-Q100 reliability standards. Its wide input range and robust HTSSOP EP package make it appropriate for body control modules, ADAS power rails, and other automotive subsystems.
What package does the TPS76733QPWP come in and how does it help with thermal management?
The TPS76733QPWP is housed in a 20-pin HTSSOP package with an exposed thermal pad (EP). The exposed pad significantly reduces junction-to-board thermal resistance, enabling the device to dissipate up to 0.904W and maintain reliable operation in thermally constrained designs.
