Key Features

  • Ultralow noise and high PSRR design optimized for noise-sensitive RF and analog circuits requiring clean power supply rails
  • Only 90 mV maximum dropout voltage (50 mV typical) at 100 mA, enabling efficient low-headroom operation close to the output rail
  • Enhanced product (EP) qualification for extended reliability in demanding industrial, automotive, and defense applications with 15-year estimated end-of-life

Applications

The TPS79133DBVREP is ideal for powering noise-sensitive analog, RF, and mixed-signal circuits in portable and industrial equipment. Its ultralow noise and high power supply rejection ratio (PSRR) make it particularly suitable for RF front-end modules, ADC references, and precision sensor power supplies. The enhanced-product qualification ensures long-term availability and reliability for designs with extended production lifetimes.

Frequently Asked Questions

What is the dropout voltage of the TPS79133DBVREP?

The TPS79133DBVREP has a typical dropout voltage of 50 mV and a maximum dropout voltage of 90 mV at 100 mA output current. This very low dropout allows the regulator to maintain its 3.3V output even when the input voltage is only slightly above the output, maximizing efficiency in battery-powered designs.

What input voltage range does the TPS79133DBVREP support?

The TPS79133DBVREP accepts an input voltage range of 3.456V to 5.5V, with an absolute maximum input voltage of 6V. This makes it compatible with single-cell Li-ion batteries and standard 5V USB power supplies commonly used in portable and embedded applications.

Why is the TPS79133DBVREP recommended for RF and analog applications?

The TPS79133DBVREP features ultralow output noise and high power supply rejection ratio (PSRR), which are critical for minimizing interference in RF circuits, ADCs, DACs, and precision amplifiers. The clean power supply helps maintain signal integrity and reduces spurious noise in sensitive analog signal chains.

What does the 'EP' suffix mean in TPS79133DBVREP and what package does it use?

The 'EP' suffix stands for Enhanced Product, indicating the device meets extended reliability and longevity standards suitable for industrial, automotive, and aerospace designs. The part comes in a compact 5-pin SOT-23 package, occupying minimal PCB space while delivering full LDO functionality.
