LX8385B-00CP

The LX8385B-00CP is an integrated voltage regulator in the PMIC - Voltage Regulators - Linear family from ON Semiconductor. It is a monolithic integrated circuit consisting of two low dropout (LDO) linear voltage regulator and one high voltage diode regulator. It is designed to meet the ever-evolving requirements of portable electronic systems while providing superior regulation accuracy, low quiescent current, low temperature coefficient and fast transient response time. It offers low noise, excellent line and load transient response, low dropout voltage and low ground current.

The LX8385B-00CP is designed to provide a regulated output voltage even when the input voltage is at a very low level. It features a selectable output voltage up to 8V and a wide operating temperature range of -40℃ to +85℃. It enables highly stable and reliable performance under extreme environmental conditions such as dropouts and surges. It offers low output ripple noise and is integrated with over-current, over-temperature and reverse current protection.

The working principle of the LX8385B-00CP is based on a combination of two linear voltage regulators and one high voltage diode regulator. The linear voltage regulators provide a stable, low noise and low dropout voltage for the output voltage, generated from inputs that can range between 2.7V and 16.5V and outputs up to 8V. This ensures that even when input voltage drops below the set value, the output remains stable and constant. The regulator is designed to optimize the quiescent current, resulting in improved efficiency and power savings.

The built-in diode regulator maintains the output voltage without further dissipating the power. The diode regulator can handle high input voltages up to 15V and provides fast transient response over a wide operating temperature range. It also has excellent line and load transient response, providing precision voltage output. The diode also provides reliable protection against short circuits and over-voltage conditions.

The LX8385B-00CP is an ideal choice for critical and demanding applications ranging from portable electronic systems such as smartphones, tablet computers and digital cameras to industrial applications such as solar energy inverter and LED lighting systems. In addition, this voltage regulator is also suitable for audio, automotive, telecommunications and computer systems.

The LX8385B-00CP is a versatile integrated linear voltage regulator that provides low dropout voltage, superb line and load transient response and excellent accuracy in a tiny package. It offers superior performance and reliability, making it suitable for a wide range of applications, including portable handhelds, automotive, audio and industrial systems.
