Frequently Asked Questions

What is the minimum input voltage required to maintain regulation for TPS79933DRVRG4?

The TPS79933DRVRG4 requires a minimum input voltage of 3.46 V to maintain a regulated 3.3 V output. This is determined by the 3.3 V output plus the typical 100 mV dropout voltage, making it suitable for single-cell Li-ion applications where the battery voltage can drop close to 3.5 V near end-of-life.

How much output current can TPS79933DRVRG4 supply continuously?

TPS79933DRVRG4 can supply up to 200 mA of continuous output current at 3.3 V. This capacity makes it appropriate for powering microcontrollers, RF transceivers, sensors, and other low-to-medium power digital and analog ICs commonly found in portable and IoT designs.

Which applications benefit most from the low-noise characteristics of TPS79933DRVRG4?

Applications such as GPS receivers, Bluetooth and Zigbee radios, precision ADC circuits, and audio codecs benefit most from the low output noise of TPS79933DRVRG4. The device's noise performance, combined with its 200 mA current capacity and 3.3 V fixed output, makes it a strong candidate for powering the analog supply rails in mixed-signal systems operating from -40°C to 125°C.

How does the 6-pin WSON package of TPS79933DRVRG4 aid thermal management on a PCB?

The 6-pin WSON package includes an exposed thermal pad on the underside that conducts heat directly to the PCB copper plane, significantly reducing thermal resistance compared to standard no-lead packages. At 200 mA output current, this helps keep junction temperatures well within the device's rated range, supporting reliable operation across the full -40°C to 125°C industrial temperature range.

When would TPS79933DRVRG4 be preferred over a switching regulator for a 3.3 V supply?

TPS79933DRVRG4 is preferred over a switching regulator when minimizing output ripple and electromagnetic interference is critical, such as in RF front-ends or sensitive analog measurement circuits. Because it dissipates excess voltage as heat across its dropout transistor, it is most efficient when the input-to-output differential is small — typically less than 1 V — keeping power dissipation below 200 mW at the 200 mA rated current.
