42141 POSITIVE REGULATOR + 5 VOLTS Mii
Features:
- Output noise typically less than 3 µv
- Output current up to 150 mA
- Input voltage up to 30V
- Internal short circuit protection, foldback and current limiting Applications:
- Down hole oil exploration
- Military & high reliability applications where a hermetically sealed product for harsh environments is required
DESCRIPTION
This regulator is fabricated using hybrid techniques and will operate at temperatures up to 200°C. This device is complete with internal short circuit protection which includes voltage shutdown and current foldback. The new 42141 series regulator normally does 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.
