POWER MANAGEMENT Description
T h e EZ1082 is a high performance positive voltage regulator designed for use in applications requiring low dropout performance at 10A. Additionally, the EZ1082 provides excellent regulation over variations in line, load and temperature. Features include 1.3V dropout at 10A, fast transient response, internal current limiting and thermal shutdown protection of the output device. The EZ1082 series are t h r e e terminal regulators with fixed and adjustable v o l t a g e options available in the popular TO-220 package. T h e EZ1082 is an excellent choice for powering m i c r o p r o c e s s o r systems. Using an LDO eliminates MOSFETs and inductors saving both space and cost. An LDO also provides better transient response with no ripple to the load.
