2 / 17 page Micrel, Inc. LP2950/2951 September 2008 2 M9999-091208 Additional features available with the LP2951 also include an error flag output that warns of a low output voltage, which is often due to failing batteries on the input. This may also be used as a power-on reset. A logic-compatible shutdown input is also available which enables the regulator to be switched on and off. This part may also be pin-strapped for a 5V output, or programmed from 1.24V to 29V with the use of two external resistors. The LP2950 is available as either a -02 or -03 version. The -02 and -03 versions are guaranteed for junction temperatures from –40°C to +125°C; the -02 version has a tighter output and reference voltage specification range over temperature. The LP2951 is available as an -02 or -03 version. The LP2950 and LP2951 have a tight initial tolerance (0.5% typical), a very low output voltage temperature coefficient which allows use as a low-power voltage reference, and extremely good load and line regulation (0.05% typical). This greatly reduces the error in the overall circuit, and is the result of careful design techniques and process control. ___________________________________________________________________________________________________________ Ordering Information Part Number Voltage Accuracy Junction Temperature Range Package Lead Finish LP2950-02BZ* 5.0V 0.5% –40° to +125°C 3-Pin TO-92 Plastic Standard LP2950-03BZ* 5.0V 1.0% –40° to +125°C 3-Pin TO-92 Plastic Standard LP2951-02BM 5.0V 0.5% –40° to +125°C 8-Pin SOIC Standard LP2951-03BM 5.0V 1.0% –40° to +125°C 8-Pin SOIC Standard LP2951-02BN 5.0V 0.5% –40° to +125°C 8-Pin Plastic DIP Standard LP2951-03BN** 5.0V 1.0% –40° to +125°C 8-Pin Plastic DIP Standard LP2951-02YM 5.0V 0.5% –40° to +125°C 8-Pin SOIC Pb-Free LP2951-03YM 5.0V 1.0% –40° to +125°C 8-Pin SOIC Pb-Free LP2951-02YN 5.0V 0.5% –40° to +125°C 8-Pin Plastic DIP Pb-Free Note: * TO-92 Package discontinuance notification issued September 2007.
