The ISL75052SEHEVAL1Z evaluation board provides a simple platform to evaluate the performance of the ISL75052SEH, a radiation hardened, high-performance, adjustable, low-voltage, high-current, low-dropout linear regulator (LDO) specified at 1.5A rated output current for input voltages from 4.0V to 13.2V. The LDO outputs can be adjusted from 0.6V to 12.7V by means of two preset resistors. Salient features of the part include:

  • TID, ELDRS and SEE rated
  • Very fast load transient response
  • ±2.0% guaranteed VOUT accuracy over line, load and temperature
  • Typical dropout of 225mV at 1.5A
  • EN feature
  • PG feature
  • OCP feature
  • Short-circuit and over-temperature protection


  • DLA SMD 5962-13220
  • Input supply range 4.0V to 13.2V
  • Output current up to 1.5A at a TJ = +150 °C
  • Best-in-class accuracy ±1.5%
    • Over line, load and temperature
  • Ultra-low dropout:
    • 75mV dropout (typ.) at 0.5A
    • 225mV dropout (typ.) at 1.5A
  • Noise of 100µVRMS (typ.) between 300Hz to 300kHz


  • LDO regulator for space power systems
  • DSP, FPGA and microprocessor core power supplies
  • Post regulation of SMPS and down-hole drilling
