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
