... This feature, among others, makes the LP2950 and LP2951 ideally suited for use in battery-powered systems. Available in a 3-pin TO-92 package, the LP2950 is pin- compatible with the older 5V regulators. Additional system functions, such as programmable output voltage and logic- controlled shutdown, are available in the 8-pin DIP and 8- pin SOIC versions of the LP2951 ...

... AC noise present at the output. One method is to reduce the regulator bandwidth by increasing the size of the output capacitor. This is the only method by which noise can be reduced on the 3-pin LP2950 and is relatively inefficient, as increasing the capacitor from 1µF to 220µF only decreases the noise from 430µV to 160µ ...
