1.25V Adjustable Shunt Regulator
B432
Description
The B432 is a three terminal adjustable shunt regulator with
thermal stability of 50ppm/°C. The output voltage can be
adjusted to any value from 1.25V (VREF) to 15V with two
external resistors. The B432 is an ideal voltage reference in an
isolated feedback circuit for 3.0V switch mode power supplies
The B432 shunt regulator is available with three voltage
tolerances (0.5%, 1.0% and 2.0%) and three package options
(SOT-23-3, TO-92, 8SOIC). This allows the designer the
opportunity to select the optimum combination of cost and
performance for their application.
Features
• Low voltage operation (down to 1.25V)
• Wide operating current….1mA to 100mA
• Trimmed bandgap design ± 0.5%
• Wide temperature range 0°C to +105°C
• Available in SOT-23-3, TO-92 , 8SOIC
• Upgrade for TLV431A & Cross AS432
Applications
• Switching Power Supplies
• Adjustable Power Supplies
• Linear Regulators
• Battery Powered Equipment
• Monitors, TV, VCR
• Instrumentation
