Frequently Asked Questions
What is the output voltage and current of the TPS71921-22DRVT?
The TPS71921-22DRVT provides two fixed 2.2V regulated outputs, each capable of sourcing up to 200mA. The input voltage range is 2.7V to 6.5V, making it compatible with single-cell Li-ion batteries and 3.3V or 5V supply rails.
What is the dropout voltage of the TPS71921-22DRVT?
The TPS71921-22DRVT has a typical dropout voltage of 0.23V and a maximum of 0.4V at full 200mA load. This low dropout characteristic allows the device to regulate properly even when the input supply is only slightly above the 2.2V output voltage.
What package does the TPS71921-22DRVT come in and what are its dimensions?
The TPS71921-22DRVT comes in a 6-pin WSON (2×2mm) no-lead package, classified under Small Outline No-lead (SON) family. Its 2×2mm footprint and 0.65mm pitch make it suitable for high-density PCB layouts in wearables and portable devices.
What are typical applications for the TPS71921-22DRVT?
Typical applications include portable consumer electronics, IoT sensor nodes, Bluetooth and Wi-Fi modules, microcontroller I/O power supplies, wearable health monitors, and industrial handhelds. The dual 2.2V output is ideal for powering two separate analog or digital subsystems simultaneously.
Is the TPS71921-22DRVT RoHS compliant and what is its EOL status?
Yes, the TPS71921-22DRVT is Pb-free (RoHS compliant) as indicated by its Pbfree Code. The YTEOL rating is 15, indicating it is an active production part with a long remaining product life, making it a reliable choice for new designs.
