Description

The R1525 is a low supply current voltage regulator featuring 200 mA output current and up to 42 V input voltage. By providing excellent noise immunity to externally generated RF noise, this device is suitable for the automotive power source for car accessories and control unit used under the electromagnetic environment. This regulator can be used under high temperature environment. It offers the maximum operating temperature of 105°C for consumer applications, and 125°C for industrial and automotive applications. This product for industrial applications is characterized to −50°C, and operates in a wide temperature range from low temperature to high temperature.

Key Benefits

  • Achieves low-supply current of 2.2 µA (Typ.) with the LDO regulator at maximum rating 50 V (Peak Inrush Voltage: 60 V).
  • Ensures the design margin by the output voltage with high-accuracy of ±0.6% (Ta=25°C).
  • Protects the output voltage variations in high-frequency noise band (10 MHz to 1 GHz).
