Mii

MICROCIRCUITS DIVISION

Features:

• Operating temperature +200ºC

• Output current to 1.0 A

• Input voltage to +38 V

• Output voltage to +30V

• Internal short circuit protection, foldback and

current limiting

• Isolated TO-258 package

Applications:

• Military and Hi Rel Industrial harsh environment

applications where hermetically sealed product is

required

• Down hole applications

DESCRIPTION

The 42118 series of fixed voltage regulators covers the output voltage range from +5 VDC through +30 VDC. These voltage

regulators are fabricated using hybrid techniques and will operate at temperatures up to +200ºC. These devices are

complete with internal short circuit protection, which includes voltage shutdown and current foldback. It is strongly

recommended that input and output capacitors be added as close to the case as possible. A 2µf capacitor should be added

to the input and minimum of 1.5µf capacitor should be added to the output. See typical connection diagram below.
