DESCRIPTION:
The MSK5142 series regulators offer a low 340mV dropout voltage while supplying to 3A of output current. With fast
transient response, these regulators have very low output noise. Excellent line and load regulation characteristics ensure
accurate performance for multiple applications with a low operating quiescent current of 1mA. These regulators offer
internal short circuit current limit, thermal limiting and reverse current protection which eliminates the need for external
components and excessive derating. The MSK5142 series regulators are available in a hermetically sealed space efficient
TO-257 package with multiple lead form options.
