The LX1662CN is a special purpose three-terminal adjustable voltage regulator designed to provide cost-effective, precision power supply solutions. Available in a minimum package configuration, this integrated circuit voltage regulator offers the ultimate in convenience for any application requiring an adjustable power supply. It is widely used for handheld device and industrial applications, especially where high-current voltage regulation is needed.

The LX1662CN voltage regulator integrates many critical components required for accurate voltage regulation. Its primary component is a low bias current operational amplifier (op amp) based on a differential pair of MOSFET transistors. This op amp provides a low output impedance, excellent DC performance and accuracy over a wide temperature range. The LX1662CN also integrates two MOSFETs to provide a constant current sensing (correction) load. The device has wide input voltage range and delivers up to 1A output current.

The working principle of the LX1662CN is quite simple. Its op amp is the key component that enables the regulation of an output voltage. The LX1662CN takes a reference voltage from an internal voltage divider and senses the output voltage from the power supply. The sensed output voltage (Vout) is then compared to the reference voltage Vref. If Vout is greater than Vref, the op amp will drive more current into the load, causing Vout to decrease. On the other hand, if Vout is lower than Vref, the op amp will draw current away from the load, causing Vout to increase. This process is repeated until the output voltage is in line with the reference voltage, ensuring that the power supply is stable at all times.

The LX1662CN is a cost-effective solution for applications requiring an adjustable power supply. Its wide input voltage range, low output impedance and low bias current make it ideal for managing multiple low-voltage DC power supplies. The device also provides excellent accuracy through an internal voltage divider and current sensing load, making it an excellent solution for applications requiring precision regulation. The LX1662CN is available in the minimum package configuration, making it a space-saving solution for any application.
