Description
.eatures
The EZ55Z3L voltage regulators are monolithic integrated
circuits designed for use in applications requiring a well
regulated positive output voltage with low input-to-
output differential voltage requirements.
Outstanding features include full power usage up to
250mA of load current, internal current limiting and
thermal shutdown. Safe area protection on the die is
also included, providing protection of the series pass
transistor under most operating conditions. The SOT-223
package is available for cost effective applications.
