LP2950CZ-5.0/NOPB

The LP2950CZ-5.0/NOPB is a 5V 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). Furthermore, the quiescent current of the 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.
