Overview

The μPC1943, 1944 are adjustable high precision shunt regulators. The output voltage can be set to any value between reference voltage (1. 26 V) and 24 V by two external resistors. These ICs can apply to error amplifier of switching regulators.

  • Low voltage operation.: VREF ≤ VOUT ≤ 24 V
  • High accuracy.: VREF = 1.26 V ± 2.4%
  • Adjustable output voltage by two external resistors.
  • Pin compatible with μPC1093. (μPC1944)
