FEATURES - - - - - - - - Low Voltage Operation 1.24V Trimmed Bandgap to 0.5%/ 1% Wide Operating Current 1m A to 100m A Extended Temperature Range 0°C to 105°C Adjustable Output Voltage VREF to 18V Low Temperature Coefficient 50 ppm/°C Offered in TO-92, SOIC, SOT-89, SOT-23-3 & SOT-23-5 Improved Replacement in Performance for TLV431 APPLICATIONS - - - - - - 3.0V to 3.3V Switching Power Supplies Adjustable Supplies Error Amplifiers Single Supply Amplifier Monitors / VCR / TV Personal puters PRODUCT DESCRIPTION The AS432 is a 3-terminal Adjustable Shunt Voltage Regulator providing a highly accurate 1.24V bandgap reference with 0.5% tolerance. The AS432 thermal stability, wide operating current (80m A) and temperature range (0°C to 105°C) makes it suitable for abroad range of applications. AS432 tolerance of 0.5% is proven to be sufficient to overe other errors in the system to virtually eliminate the need for trimming in the power supply manufactures assembly line and contribute a significant cost savings. The AS432 is an ideal voltage reference in an isolated feedback circuit for 3.0V to 3.3V switching mode power supplies. AS432 offers many advantages over TLV431, such as, wider output voltage up to 18V vs. 6V, output current of 80m A vs. 15m A, and a wider temperature range with tighter tolerance down to 0.5%.
