What are the key features of TPS71933-33DRVTG4?

  • Dual-output 3.3 V LDO in a 6-pin SON package powers two independent supply rails with a single compact IC
  • 0.23 V typical dropout voltage at 200 mA maximizes output regulation even when input supply is nearly depleted
  • ±2.5% output voltage accuracy ensures stable 3.3 V regulation across the full operating temperature range

What is TPS71933-33DRVTG4 used for?

The TPS71933-33DRVTG4 is ideal for space-constrained portable devices, IoT sensor modules, and wireless communication boards that require two independent 3.3 V regulated rails from a single 3.7 V to 6.5 V supply. Its low dropout voltage and dual-output capability simplify power tree design in Bluetooth and Wi-Fi modules where separate analog and digital supply domains are required.

Frequently Asked Questions

How does the dual-output topology of the TPS71933-33DRVTG4 simplify power supply design for wireless sensor modules?

By providing two independent 3.3 V LDO outputs from a single 6-pin package, the TPS71933-33DRVTG4 eliminates the need for a second discrete LDO when separate analog and digital 3.3 V domains are required. This saves up to 10 mm² of PCB area compared to using two single-output SOT-23 devices, which matters critically in miniaturized IoT nodes and wearable sensor designs.

At the end of a Li-ion battery discharge cycle, how does the 0.23 V typical dropout of the TPS71933-33DRVTG4 extend usable battery life?

With a nominal dropout voltage of only 0.23 V, the TPS71933-33DRVTG4 maintains a regulated 3.3 V output until the input supply falls to approximately 3.53 V. This means the device continues to operate for a longer portion of the Li-ion discharge curve compared to devices with 0.5 V or higher dropout, effectively adding usable capacity equivalent to several percent of battery runtime in typical applications.

For a design requiring ±2.5% output voltage accuracy, how does the TPS71933-33DRVTG4 compare to general-purpose LDOs with ±3% tolerance?

The ±2.5% output accuracy of the TPS71933-33DRVTG4 keeps the 3.3 V output within a window of 3.2175 V to 3.3825 V across temperature and load, which provides an additional 0.5% margin over ±3% devices when the downstream circuit imposes tight supply tolerance requirements. This tighter specification reduces the risk of 3.3 V logic and ADC reference circuits drifting outside their own operating voltage windows.
