MICROCIRCUIT DATA SHEET Original Creation Date: 08/01/95 Last Update Date: 05/19/98 Last Major Revision Date: 01/21/97 MJLP2951-X REV 1B1 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.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. The maximum power dissipation msut be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number given in the Absolute Maximum Ratings, whichever is lower. May exceed input supply voltage. When used in dual-supply systems where the output terminal sees loads returned to a negative supply, the output voltage should be diode-clamped to ground. 3 MICROCIRCUIT DATA SHEET MJLP2951-X REV 1B1 Electrical Characteristics DC PARAMETERS (The following conditions apply to all the following parameters, unless otherwise specified.)
