AN1432MS
Variable output, low voltage operation shunt regulator IC
s Overview
The AN1432MS is a low voltage operation and posi-
tive voltage variable output type shunt regulator IC. Since
the output voltage is adjustable from approximately 1.26
V to 15 V, it is suitable for a power supply of small-sized
3 V-system portable equipment. Also, it contributes to the
miniaturization of set equipment by the adoption of the
small type surface mounting package.
s Features
• High precision reference voltage: 1.26 V (allowance:
±2%)
• Low voltage operation: 1.26 V to 15 V
• Small type surface mounting package
s Applications
• Portable telephone, PHS, office automation equipment,
and other small-sized portable equipment
