Voltage Regulators
AN1432NT
Variable output, low voltage operation shunt regulator
1
I
Overview
The AN1432NT is a low voltage operation and posi-
tive voltage variable output type shunt regulator. Since the
output voltage is adjustable from approximately 1.275 V to
14 V, it is suitable for a power supply of small-sized 3 V-
system portable equipment.
I
Features
High accuracy reference voltage:
1.275 V (allowance:
±
2%)
Low voltage operation: 1.275 V to 14 V
I
Applications
Office automation equipment and other small-sized por-
table equipment
Note) The value of reference voltage and the package differ from AN1432MS.
