  • Automotive
  • PLP
  • AEC-Q100
  • RoHS

R5112 is an ultra-low supply current voltage regulator with a voltage detector featuring 200 mA output current and 42 V input voltage. This device consists of an Output Short-circuit Protection Circuit, an Overcurrent Protection Circuit, and a Thermal Shutdown Circuit in addition to the basic regulator circuits.

It offers a wide range of operating temperature of −40°C to 105°C for consumer applications, and −40°C to 125°C for industrial and automotive applications. The maximum input voltage is 42 V. The output voltages are internally fixed at either of the following: 1.8 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V, 3.4 V, or 5.0 V. The output voltage accuracy is ±0.6%. The detector threshold accuracy of the voltage detector is ±0.6%. This device is offered in an 8-pin HSOP-8E package with high power dissipation.
