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.

V^REF= 1.26 V ± 2.4 %

V^REF≤ V^OUT≤ 24 V
