UPC1944
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 patible to µ PC1093. VREF = 1.26 V ± 2.4 % VREF ≤ VOUT ≤ 24 V
