Key Features

  • 250mA output current with only 25µA quiescent current for maximum battery life
  • Ultra-low 0.13V typical dropout voltage enables efficient low-headroom regulation
  • Fast transient response optimized for RF and wireless applications
  • Wide 2V to 5.5V input voltage range suits diverse power supply designs
  • Compact 6-pin Small Outline No-lead (SON) package for space-constrained PCB layouts

Applications

The TPS72728DSER is ideally suited for RF and wireless communication modules where stable, low-noise power is critical, such as Bluetooth, Zigbee, and sub-GHz IoT devices. Its ultralow quiescent current makes it an excellent choice for battery-powered wearables and sensor nodes that require extended runtime. It also serves well in portable consumer electronics and medical monitoring devices where compact size and high efficiency under light loads are essential.

Frequently Asked Questions

What is the input voltage range and maximum output current of the TPS72728DSER?

The TPS72728DSER accepts an input voltage from 2V to 5.5V and delivers up to 250mA of output current. Its absolute maximum input voltage is 6V, providing a small margin above the operating range for transient protection.

Why is the TPS72728DSER recommended for RF and wireless applications?

This LDO features an ultralow quiescent current of approximately 25µA and fast transient response, which together minimize power consumption and maintain a stable supply voltage even when RF loads switch rapidly. These characteristics reduce noise coupling into sensitive RF front-end circuits.

What is the typical dropout voltage of the TPS72728DSER and why does it matter?

The typical dropout voltage is 0.13V with a maximum of 0.2V at full load. A low dropout voltage means the regulator can maintain its regulated output with very little difference between input and output, allowing efficient operation from nearly depleted batteries or tightly regulated upstream supplies.

What package does the TPS72728DSER use and what are its dimensions?

The TPS72728DSER comes in a 6-pin Small Outline No-lead (SON / DSER) package, a compact surface-mount form factor suited for high-density PCB designs. The JESD-30 code is S-PDSO-N6, confirming a 6-lead plastic small-outline no-lead configuration commonly used in space-constrained applications.

Is the TPS72728DSER RoHS compliant and what is its end-of-life status?

Yes, the TPS72728DSER is Pb-free (RoHS compliant) as indicated by its Pbfree Code. Its YTEOL value of 15 reflects Texas Instruments' product lifecycle indicator, and the part remains in active production and available for purchase from authorized distributors.
