The LX1665CDW is a special purpose voltage regulator specifically designed to provide ultra-low noise and low dropout in power conversion applications. It is a true linear regulator that provides smooth, noisy-free output and can operate from input voltages up to 8V. It also features low noise ripple for power output up to 75mA and can deliver up to 60mA with optimum efficiency.

The LX1665CDW is a highly integrated device that includes two high performance PWM control/protection circuits. These circuits feature diode emulation, overcurrent and short-circuit protection, as well as pulse-width modulation (PWM) control that keeps the input current in tight tolerance. The device also employs a low quiescent current power down mode for improved overall efficiency.

The working principle behind the LX1665CDW is based on high-bandwidth voltage ripple cancellation. It consists of two stepped-down voltage regulation (SR) stages and a low-noise reference voltage (RV) circuit. The first SR stage works as a low-ripple regulator and the second SR stage serves as a high-voltage regulator. These two stages together generate a voltage that is equal to the reference voltage. The reference voltage circuit precisely controls the voltage level and ensures ultra-low noise output over a wide range of operating conditions.

The LX1665CDW is designed for use in a wide range of applications, including ultra-low noise power supplies, battery chargers, PC and notebook supplies and medical instrumentation, as well as automotive, industrial and military systems. Its small size and low quiescent current make it ideal for portable electronics, such as cell phones and PDAs. Furthermore, its low dropout and integrated protection features ensure reliable operation in any operating condition.

In summary, the LX1665CDW is a high performance, specialized voltage regulator designed to provide ultra-low noise and low dropout in power conversion applications. With its PWM control/protection circuits, low quiescent current power down mode and low noise ripple, it is the ideal choice for a wide range of applications, including ultra-low noise power supplies, battery chargers, PC and notebook supplies and automotive, industrial and military systems.
