LD3985M30R

LD3985M30R is an efficient linear voltage regulator from ON Semiconductor that is mainly used for the efficient power conversion from 2.7V to 5.5V DC. It is one of the most popular low-dropout regulators or LDO, and can offer up to 1A of output current for single or dual output configurations. The regulator also supplies very low output noise and fast transient response times.

The LDO\'s operating temperature range extends from -40 degrees Celsius to 125 degrees Celsius, and its output to ground impedance is very low (typically 10 mΩ). The regulator also features excellent regulation across line and load variations, with very low output voltage ripple of 0.6 mV RMS (max).

The LD3985M30R is commonly used in automotive applications, such as in powertrain, infotainment and safety systems. It is also well suited for low quiescent current designs and allows for high efficiency across a wide temperature range. It is also particularly useful for applications that rely on high reliability, such as for medical devices.

From an operational standpoint, the LDO works by being inserted between the input power source, typically a battery, and the load that needs to be powered. When operating at a load current of up to 1A, the regulator features a dropout voltage of 0.12V at the upper end of the operating temperature range. In addition, the input voltage can range from 2.7V to 5.5V, and the output voltage can be set between 0.88V to 5.5V using external resistors.

The regulator also allows for up to 1A of output current and 0.6 mV of output voltage ripple, making it well suited for a variety of applications. The quiescent current of the device is also very low, making it suitable for low power applications. Furthermore, the LDO allows for thermal shutdown and reverse current protection, which helps keep the regulator from becoming damaged due to overcurrent.

The high performance, efficiency, and protection features make the LD3985M30R an excellent choice for applications requiring energy efficiency and high reliability. With its ability to provide up to 1A of output current, it is a great choice for automotive applications and other cost-sensitive applications.
