AMS3121

General Description The AMS3121 is a high performance linear regulator with very low dropout voltage and excellent transient response. It is designed to operate with wide input voltage range of 1.5 – 7Volts making it ideal for two step conversion while maintaining high efficiency for many power sensitive applications. The device is capable of supplying 2A of output current with a typical dropout voltage of 550mV at 2A. The product is only available in a fixed output voltage option. The product includes complete short-circuit and thermal protection. The combination of these two internal protection circuits gives the device a comprehensive safety system to safe guard against extreme adverse operating conditions. The AMS3121 is available in both 3-pin TO-220 and TO-263 packages, and it is rated for -40°C to +125°C temperature range.
