General 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.
