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.
FEATURES
Low voltage operation and High accuracy.
Adjustable output voltage by two external resistors.
Pin compatible to
