UPC1944 - ADJUSTABLE PRECISION SHUNT REGULATORS

General Description

The µ PC1943,1944 are adjustable precision shunt regulators with guaranteed thermal stability.

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.

Key Features

  • Low voltage operation and High accuracy.
  • Adjustable output voltage by two external resistors.
  • Pin compatible to µ PC1093. VREF = 1.26 V ± 2.4 % VREF ≤ VOUT ≤ 24 V.
