The LP2951CMM-3.3/NOPB is a low power voltage regulator from Texas Instruments which provides stable three-terminal positive-voltage regulation from 3.3V with a low ripple. This voltage regulator utilizes a precision voltage reference and a phase locked loop (PLL) for peak current limiting and thermal shut-down protection. It can supply up to 100mA of output current and has a typical dropout voltage of 0.07V at 25°C.

It is a fixed low dropout linear regulator with a ceramic capacitor that provides better filtering of noise and a higher output capacitance than other linear regulators. Its typical application field includes RFID, wireless transceiver, component audio, data acquisition, memory, logic and microprocessor circuits, and automotive applications.

The LP2951CMM-3.3/NOPB working principle is based on a three-terminal positive voltage regulator with a fixed output voltage of 3.3V and an output voltage accuracy of 0.05% or 0.4V, whichever is greater. It provides load current up to 100mA in a low dropout voltage of less than 0.07V at 25°C. It features a precision voltage reference and a phase locked loop (PLL) for peak current limiting and thermal shut-down protection.

The LP2951CMM-3.3/NOPB has an adjustable current limit and current sensing, a low-noise voltage output, and an audio-frequency quiescent current of 750nA at 25°C. It also has an over-current protection feature, which protects against output current exceeding the device\'s maximum rating. In addition, it has auto reset function and a power OK flag. It also features a fast transient response and low output noise, making it suitable for high-speed applications.

The LP2951CMM-3.3/NOPB is suitable for a very wide range of battery-powered and other applications courtesy of its features such as fast transient response, high PSRR, good line and load regulation, fast safe-instantaneous current limit, and low power dissipation. The package includes an exposed pad for enhanced thermal performance and a lead-free finishing.
