DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
µ PC1943,1944
ADJUSTABLE PRECISION SHUNT REGULATORS
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 µ PC1093.
VREF = 1.26 V ± 2.4 %
VREF VOUT 24 V
