... March 17, 1998 DESCRIPTION The LP2951A is an improved version of the LP2951 and features tighter tolerance on the output voltage and reference voltage specifications. Both the LP2951 and LP2951A feature 150mA output current capability. The LP2951 series of low power voltage regulators have low quiescent current and low dropout voltage. ...

... March 17, 1998 PRINCIPLES OF OPERATION (LP2951 AND LP2951A) Setting the Output Voltage The LP2951(A) can be set to deliver any output voltage from 1.24V to 30V by using an external voltage divider. In addition, an internal voltage divider is provided output is desired. To use the internal voltage di- vider, simply connect the sense pin to the output and the tap pin to the feedback pin (see block diagram) ...

... March 17, 1998 PRINCIPLES OF OPERATION (LP2951 and LP2951A) (cont.) Reducing Output Noise In ultra-quiet systems, or when the LP2951(A) is being used as a reference, it may be desirable to perform additional output filtering to reduce noise. While this can be done simply using larger capacitors on the out- put, that solution tends to be bulky and expensive, and eventually, with huge capacitors (> ...
