DESCRIPTION:
The MSK 5046RH series are high efficiency, 4 amp, radiation hardened switching regulators. The output voltage is
configured for 1.5V, 2.5V, 3.0V, 3.3V or 5.0V internally with a tolerance of 1% at 1.5 amps. The operating frequency
of the MSK 5046RH is 300KHz. A low quiescent current and greater than TBD operating efficiency keep the total
internal power dissipation of the MSK 5046RH down to an absolute minimum. The device is packaged in a hermetic
power package for high reliability applications, and is available fully compliant to MIL-PRF-38534 Class H or K.
