Texas Instruments LP2950CZ-3.0/NOPB LP2950CZ-3.0/NOPB Fixed LDO Voltage Regulator 3.4V to 30V 380mV Dropout 3Vout 100mAout TO-92-3

The LP2950CZ-3.0 is a series of fixed Micropower Voltage Regulator with very low quiescent current (75µA typical) and very low dropout voltage (typical 40mV at light loads and 380mV at 100mA). This regulator is ideally suited for use in battery-powered systems. Furthermore, the quiescent current of the LP2950 regulator increases only slightly in dropout, prolonging battery life. Careful design of the regulator has minimized all contributions to the error budget. This includes a tight initial tolerance (0.5% typical), extremely good load and line regulation (.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.
