The output voltage can be set to any value between VREF (approximately 2.5V) to 18V with two external resistors (see application circuit). This device has a typical output impedance of 0.2 ohms. Active output circuitry provides very sharp turn-on characteristics, making this device an excellent replacement for Zener diodes in many applications. The SS431 is characterized for operation from 0°C to 105°C, and three package options (SOT-23, SOT-89, and TO-92) allow the designer the opportunity to select the proper package for his application. The SS431 is available with a Pb-free lead finish DESCRIPTION Low voltage operation (2.5V) Adjustable output voltage from VO = V REF to 18V Wide operating current range from 0.4mA to 100mA Low dynamic output impedance 0.5 Ω max. ESD rating is 5.5kV (per MIL-STD 883D) Linear Regulators Adjustable Supplies Switching Power Supplies Battery Operated Computers Instrumentation Computer Disk Drives FEATURES APPLICATIONS Rev.2.02 3/11/2004 - order as SS431Gxx. Pb-free lead finish available. Cathode Reference Anode 3 2 1 |
