The Texas Instruments LP2951-50QDRQ1 is a low-dropout (LDO) voltage regulator with a single output of 5V, 100mA and a fixed output voltage of 5.0V. It features an on-chip adjustable current limiting and thermal shutdown. It is designed with an ultra low quiescent current of only 2µA to enable a very low power, low supplied current consumption. The LP2951-50QDRQ1 is ideal for designs such as battery-powered applications, portable handhelds, computer peripherals, and cell phone applications. It offers low noise, low dropout voltage, high accuracy, low quiescent current, and low output voltage ripple.
