DESCRIPTION
The EZ158X family of high performance positive
voltage regulators are designed for use in applications
requiring very low dropout voltage at 7, 5, 3 and 1.5
amps. When supplying 2.5V on motherboards where
both 5V and 3.3V supplies are available, the superior
dropout characteristics of the EZ158X result in reduced
heat dissipation compared to regular LDOs, thus
allowing heat sink size reduction. Additionally, the
EZ158X provides excellent regulation over variations in
line, load and temperature. Remote sense operation
allows compensating for trace, connector and other
resistive losses.
Outstanding features include very low dropout
performance at rated current, fast transient response,
remote sense, internal current limiting, thermal
shutdown and safe operating area protection of the
output device. The EZ158X is a five terminal
adjustable voltage regulator available in the popular 5
pin TO-220 and TO-263 plastic packages.
