EZ55Z3L
EZ55Z3L is 0.25 AMP POSITIVE VOLTAGE REGULATORS manufactured by SEMTECH.
Description
The EZ55Z3L voltage regulators are monolithic integrated circuits designed for use in applications requiring a well regulated positive output voltage with low input-tooutput differential voltage requirements. Outstanding Features include full power usage up to 250m A 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. TO-92 and SOT-223 packages are available for cost effective applications.
