1.5A, Rad Hard, Positive, High Voltage LDO Evaluation Board


The ISL75052SEH is a high-performance, adjustable, low-voltage, high-current, low-dropout linear regulator 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

The ISL75052SEHEVAL1Z evaluation board provides a simple platform to evaluate performance of the ISL75052SEH. The device output voltage is adjustable, and jumpers are provided to easily set popular output voltages.
