HYBRID MICROELECTRONICS
PRODUCTS DIVISION
Features:
• Output current to 1.5 amps
• Input voltage to 38V
• Internal short circuit protection, foldback and
current limiting
• Storage Temperature 225°C
Applications:
• Logging while drilling
• Measuring while drilling (down-hole applications)
• Other harsh environments
• Designed to use in high temperature
environments 200°C
• 200°C Operating Temperature
• Output voltage to 30 VDC
DESCRIPTION
The 42094 series of regulators covers the voltage range from 5 VDC through 30 VDC. These regulators are fabricated using
hybrid techniques and will operate at temperatures up to 200°C case. These devices are complete with internal short circuit
protection which includes voltage shutdown and current foldback. The 42094 series regulators normally do not require any
additional components. However, for good design practice, an external filter cap should be installed at the input, as close to
the case as possible.
