产品概要
描述
The RHFL4913A is a high-performance adjustable positive voltage regulator, able to provide up to 2 A in Flat-16P and up to 3 A in SMD5C from a 3 to 12 Volt input voltage. The Flat-16P features a bottom metalization to maximize power dissipation.
The RHFL4913A features exceptional radiation hardness in both total ionization dose and single effect event. Both packages are made in ceramic and are hermetically sealed, allowing the product to be QML-V qualified for use in space. Its high reliability makes it also ideal for civil nuclear and other harsh environments.
