Overview
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.
