1.5A ULTRA LOW DROPOUT LINEAR REGULATOR AZ39151

General Description

The AZ39151 is a 1.5A, high accuracy linear voltage

regulator. It features 375mV dropout voltage at 1.5A

output current and low ground current over all operat-

ing conditions .

The AZ39151 is specifically designed for low voltage,

high current output systems, such as PC add-in cards

where their tiny dropout voltage and ground current

values are important attributes.

The AZ39151 has fixed 3.3V, 5.0V versions and

ADJ(1.25V) version.

The AZ39151 is available in TO-252-4 (PPAK) (for

fixed versions) and TO-252-5 (for adjustable version)

packages.
