Frequently Asked Questions
What is the output voltage and current of TPS79533DCQ?
The TPS79533DCQ provides a fixed 3.3V output with up to 150mA of output current. It maintains 2% output accuracy over line, load, and the full -40C to +125C temperature range, making it reliable for precision analog and digital supply rails.
What package does the TPS79533DCQ use and how many pins does it have?
The TPS79533DCQ comes in a 5-pin SC-70 package (also known as SOT-323), which is one of the smallest surface-mount packages available. This makes it ideal for space-constrained designs such as wearables, smartphones, and compact IoT modules.
What are compatible alternatives to the TPS79533DCQ?
Close alternatives include the TLV70033 (300mA, SOT-23-5, lower dropout), the LP2985-33 (150mA, SOT-23-5), and the MIC5219-3.3YM5 from Microchip (500mA, SOT-23-5). All offer 3.3V fixed output but differ in current rating, package, and quiescent current characteristics.
Is the TPS79533DCQ RoHS compliant?
Yes, the TPS79533DCQ is RoHS compliant and lead-free. It carries MSL rating of 1, meaning unlimited floor life at ambient conditions, simplifying storage and assembly in SMT production environments.
What applications is the TPS79533DCQ best suited for?
The TPS79533DCQ is optimized for portable battery-powered devices, automotive electronics, and industrial systems. Its 75uA quiescent current, 150mA output, and -40C to +125C temperature range make it suitable for IoT sensors, automotive infotainment, ADAS modules, and handheld test equipment requiring stable 3.3V regulation.
