Overview
POWER MANAGEMENT Description The SC1202 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current.
Additionally, the SC1202 series provides excellent regulation over variations due to line, load and temperature.
Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device.
The SC1202 series are three terminal regulators available in the surface mount SOT-223 package.
