HYBRID MICROELECTRONICS
PRODUCTS DIVISION
Features:
Operating temperature +200
C
Output current to 1.0 A
Input voltage to +30 V
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 +200
C. These devices are
complete with internal short circuit protection, which includes voltage shutdown and current foldback. The 42118 series
voltage regulators normally do not require any additional components. However, for good design practice, an external filter
cap of 2
F should be installed at the input, as close to the case as possible.
