概要

The RTKA214038DE0000BU evaluation board provides a simple platform to evaluate the 3.5×3.5mm 20-Ld QFN RAA214038 low-dropout linear regulator (LDO).

RAA214038 is an ultra-low noise, high PSRR LDO regulator capable of sourcing up to 3A of load current with very low dropout. The output voltage can be programmed from 0.8V to 3.95V using voltage setting pins on the IC in 50mV steps. The evaluation board has convenient jumpers to exercise these pins. External feedback resistors can still be used for higher output voltage applications, allowing the output voltage to be programmed anywhere from 0.8V to 5.1V.

The LDO operates from an input voltage of 1.4V to 6.5V without VBIAS and 1.1V to 6.5V with VBIAS.

  • Output voltage set pins easily programmed with 
    JP_VSET
  • Switch between voltage set pins or external resistor 
    divider using jumper JP_FB
  • Convenient shutdown mode function using jumper 
    JP_EN
  • Power-good (PG) indication test point
  • VBIAS banana jack or turret for applications where 
    VIN < 1.4V
  • BNC_VIN and BNC_VOUT connections for PSRR 
    and output noise testing

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
