The LP2951CDR2G is a low-power linear voltage regulator that is designed for low-voltage applications such as portable devices, embedded systems, and battery-powered systems. It offers low-noise operation and provides voltage regulation to ±1.5% of the output voltage for automotive, industrial, and audio/video applications. This device provides two independent, low-dropout linear regulators that operate from a single supply. This linear voltage regulator is available in 6-pin Mini SOT-23 packages and is available in a wide range of input and output voltages.

The LP2951CDR2G is widely used in power systems, especially in mobile and embedded platforms. The maximum current rating of a single channel is 150 mA. Other features include improved thermal performance, low power consumption and excellent power supply rejection. The LP2951CDR2G is versatile and suitable for both low voltage and high voltage applications due to its wide operational temperature range.

The LP2951CDR2G uses a variation of the traditional resistive voltage regulator (RVR) topology. The input voltage is first filtered and regulated by an input circuit that provides better power supply stability and low noise. The accuracy of the output voltage is further improved through the use of a feedback network that provides feedback to the regulated voltage. The regulated voltage passes through an output dissipation circuit before it is delivered as the output voltage. This output dissipation circuit helps ensure that all components are protected from overcurrent, overvoltage, and short circuit conditions.

The LP2951CDR2G linear voltage regulator works by dissipating the excess energy generated by current flow through its two channels. As the current through the two channels increase, the excess energy is dissipated, causing the output voltage to be regulated. The two channels are thermally protected and protected with sense pins that monitor and regulate the current levels in the two channels. In addition, the device also features a temperature-compensated output stage to maintain stable output levels over temperature variations.

The LP2951CDR2G linear voltage regulator is designed for use with mobile, embedded, and industrial applications. Its low-power operation, low-noise operation, and wide operational temperature range make it a great choice for these applications. Furthermore, its robust protection features protect the device from a variety of conditions, making it suitable for applications that demand reliable supply power. In order to ensure proper operation, it is essential to follow the data sheet specifications when configuring and calibrating the device.
