LNBH24 is a monolithic voltage regulator and interface IC for satellite receivers. It is assembled in PowerSSO-36 ePad, and specifically designed to provide the 13/18 V power supply and the 22 kHz tone signalling for two independent LNB down-converters in the antenna dishes and/or multi-switch box.

The ST715xx is a high voltage, ultra low quiescent low drop linear regulator capable of providing an output current in excess of 85 mA. It operates over an input voltage range spanning from 2.5 V to 24 V, and is stable with output ceramic capacitors. The device is suitable for low power applications and battery powered systems, with a low dropout voltage of 500 mV (at 85 mA) and a very low quiescent current of 3.8 µA (at full load).

The LED7706 is a high efficiency LED back-light driver, which includes a high efficiency monolithic boost converter and six controlled current generators (rows) specifically designed to supply LED arrays used in the back-lighting of LCD panels. The device can manage an output voltage up to 36 V (i.e. 10 white LEDs per row). In case of failure, the short-circuit or open-circuit protection feature allows to turn off the related LED row.

The ST1S12 is a step-down DC-DC converter optimized for powering low-voltage digital cores in HDD applications and, generally, to replace the high current linear solution when the power dissipation may cause high heating of the application environment. It provides up to 0.7 A over an input voltage range of 2.5 V to 5.5 V. A high switching frequency (1.7 MHz) allows the use of tiny surface-mount components. In addition to the resistor divider to set the output voltage value, only an inductor and two capacitors are required. Moreover, a low output ripple is guaranteed by the current mode PWM topology and by the use of low ESR SMD ceramic capacitors. The device is thermally protected and the current is limited to prevent damage due to accidental short-circui

This document introduces the STM6905 Quintuple ultralow voltage supervisor with push-button reset, released in January 2008. It features five voltage monitoring channels with an accurate ±1.8% voltage threshold across temperature (±1% at 25°C). It includes a primary supply (VCC) monitor and a fixed (V2IN) monitor, as well as three additional adjustable supply monitor inputs. The device also has a 600 mV internal reference, RST output (open drain), and a manual reset input. It is suitable for applications such as set-top boxes, multi-voltage systems, cable/satellite applications, computer systems, and data storage equipment.
