RT9164A

1.0A Fixed and Adjustable Low Dropout

Positive Voltage Regulators

General Description

The RT9164A series of high performance positive voltage

regulators is designed for applications requiring low

dropout performance at fully rated current. Additionally,

the RT9164A series provides excellent regulation over

variations in line and load. Outstanding features include

low dropout performance at rated current, fast transient

response, internal current-limiting, and thermal-shutdown

protection of the output device. The RT9164A series of

three terminal regulators offers fixed and adjustable

voltage options available in space-saving SOT-223,

TO-252, and TO-263 packages.
