TEXAS INSTRUMENTS  LP2951CSD-3.3/NOPB  固定电压稳压器, LDO, -300 mV至30V, 380mV压差, 3.3V输出, 100mA输出, WSON-8

The is a 3.3V fixed output low-dropout LDO Linear Regulator with very low quiescent current 75µA typical and very low-dropout LDO voltage typical 40mV at light loads and 380mV at 100mA. This device is ideally suited for use in battery-powered systems. Furthermore, the quiescent current of the device increases only slightly in dropout, prolonging battery life. Careful design of the device has minimized all contributions to the error budget. This includes a tight initial tolerance 0.5% typical, extremely good load and line regulation 0.05% typical and a very low output voltage temperature coefficient, making the part useful as a low-power voltage reference. One such feature is an error flag output which warns of a low output voltage, often due to falling batteries on the input. It may be used for a power-ON reset. A second feature is the logic-compatible shutdown input which enables the regulator to be switched on and off.
