8281 General Description

Intended for analog and digital satellite receivers, these low-noise block converter regulators (LNBRs) are monolithic linear and switching voltage regulators specifically designed to provide the power and interface signals to the LNB down converter via the coaxial cable. If the device is in standby mode (EN terminal low), the regulator output is
disabled, allowing the antenna down converters to be supplied or controlled by other satellite receivers sharing the same coaxial cable. In this mode, the device will limit the output reverse current.

The A8281SLB output is set to 13 or 18-V by the VSEL terminal. It is supplied in a 16-lead SOIC power-tab package. The power tabs are at ground potential and need no electrical isolation.

The A8282SLB output is set to 12, 13, 18, or 20-V by the VSEL terminals. Additionally, it is possible to increase the selected voltage by 1-V to compensate for the voltage drop in the coaxial cable (LLC terminal high). It is supplied in a 24-lead SOIC power-tab package. The power tabs are at ground potential and need no electrical isolation. The A8282SLB is an improved version of the A8283SLB, without a bypass switch.
