简  介:Advanced Monolithic Systems FEATURES Trimmed 0.5% Tolerance Wide Operating Current Range 0.1A to 10mA Low Reference Input Current 1.5nA Low Dynamic Output Impedance Low Output Noise Nominal Temperature Range to 125°C Temperature-Compensated: 50ppm/°C Low supply current: typ. 10A AMS421 0.5V SHUNT REGULATOR RoHS compliant APPLICATIONS Battery Powered Systems Switching Power Supplies Isolated Power Supplies Telecommunications Error Amplifiers Notebook/Personal Computer Monitors/ VCR/ TV Opto-isolator driver GENERAL DESCRIPTION The AMS421 is a four-terminal adjustable open collector shunt regulator with guaranteed temperature stability over the entire range of operation. The output voltage can be set to any value between 0.5V (VREF) and 15V by adding two external resistors. The AMS421 features 0.5% initial tolerance, low dynamic output impedance and operates over a wide current range. Due to the sharp turn-on characteristics this device is an excellent replacement for Zener diodes in many applications. AMS421 is available 5 pin SOT-23 packages.
