42051 5 A FIXED THREE TERMINAL NEGATIVE VOLTAGE REGULATORS Commercial or Military Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: • • • Output current to 5 Amps Output voltage To –34 V Internal short circuit protection Applications: • Military and Hi Rel industrial applications where hermetically sealed product is required. DESCRIPTION The 42051 series of regulators covers the voltage range from –5 V through –34 V. These regulators are fabricated using hybrid techniques. The devices are complete with internal short circuit protection which includes voltage shutdown and current fold-back. To insure circuit stability under all load combinations it is recommended that a minimum of 2.0 µF capacitance (solid tantalum) be connected between power ground and the input to the regulator.
