STMicroelectronics RHFL4913A
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.| Part No. | RHFL4913A |
