DESCRIPTION:

The MSK 5030 series are high efficiency, 4 amp, step-down switching regulators. The output voltage is configured

for 2.5V, 3.3V or 5.0V internally and the input range is 4.5V to 30V. The operating frequency of the MSK 5030 is

300KHz and is internally set. An external "soft start" capacitor allows the user to control how quickly the output

comes up to regulation voltage after the application of an input. An extremely low quiescent current of typically less

than 0.5mA and 95% operating efficiency keeps the total internal power dissipation of the MSK 5030 down to an

absolute minimum. A surface mount version, MSK 5040, is also available if desired.
