The device offers both space and cost savings in many applications such as power supply management or data acquisition systems.

LNBP21 is a monolithic voltage regulator and interface IC intended for analog and digital satellite STB receivers/SatTV, sets/PC cards. It is assembled in SO-20 and PowerSO-20 and is specifically designed to provide the power and the 13/18V, 22KHz tone signalling to the LNB down converter in the antenna or to the multiswitch box. In this application field, it offers a complete solution with extremely low component count, low power dissipation and simple design together with I2CTM standard interfacing. The IC has a built in DC/DC step-up controller that, from a single 12V supply, provides 2.5V and 13.5V voltages to meet the LNB power requirements. It also features an accurate built-in 22KHz tone oscillator for transmitting 22KHz tone signal to the LNB.

The LD1084XX is a low drop voltage regulator capable of providing up to 5A of output current.

The LD1580 is a very low dropout positive linear voltage regulator particularly suitable in applications requiring output currents up to 7 A. The LD1580 typical dropout voltage is 400 mV at 7 A while it decreases at lighter loads. This very low dropout is achieved thanks to a second input voltage pin, named VCONTROL, which is also responsible of the output power stage driving. The LD1580 is provided with an output voltage remote sense pin which reduces dramatically any output voltage variations that could occur due to load changes. The ADJ pin is still available. A small capacitor on this pin helps to improve transient response. The LD1580 also features a built-in output current limit function and a thermal shutdown protection with hysteresis which prevents from excessive power dissipation in case of insufficient heatsinking. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 2 % at the maximum output current and over the full temperature range.

L6615 is a controller IC specifically designed to achieve load sharing of paralleled and independent power supply modules in distributed power systems, by adding only few external components. Current sharing is achieved through a single wire connection (share bus) common to all of the paralleled modules.
