ADJUSTABLE MICROPOWER
VOLTAGE REGULATORS
General Description
The LP2951 is a micropower
voltage regulator with very low quiescent curent (75 uA typ.) and very low dropout
voltage (typ. 40 mV at light loads and 380 mV at 100mA). They are ideally suited for use in battery-powered systems. Furthermore, the quiescent current of the LP2951 increases only slightly in dropout, prolonging battery life. The 8-Lead LP2951 is available in plastic, ceramic dual-in-line, or metal can packages and offers additional system functions. 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. Also, the part may be pin-strapped for a 5V output or programmed from 1.24V to 29V with an external pair of resistors. Careful design of the LP2951 has minimized all contributions to the error budget. This includes a tight initial tolerance (.5% typ.), extremely good load and line regulation (.05% typ.) and a very low output
voltage temperature coefficient, making the part useful as a low-power
voltage reference.
