RT9176
1.5A Fixed and Adjustable Low Dropout Positive Voltage
Regulators
General Description
Features
The RT9176 series of high performance positive voltage
regulators is designed for applications requiring low dropout
performance at fully rated current. Additionally, the RT9176
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 RT9176 series of three terminal
regulators offers fixed and adjustable voltage options
available in space-saving SOT-223, TO-252, and TO-263
packages.
