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
