om7632nm - om7634nm 3.5 typical performance characteristics input bypass capacitors are recommended for stable operation of the om7632nm series ofregulators over the input voltage and output current ranges. output bypass capacitors will improve the transient response of the regulator. the bypass capacitors, (2.2 f on the input, 1 f on the output) should be ceramic or solid tantalum which have good high frequency characteristics. if aluminum electrolytics are used,their values should be 10 f or larger. the bypass capacitors should be mounted with the shortest leads and, if possible, directly across the regulator terminals. pin connection mechanical outline fixed output regulator basic current regulator 12 3 .500 .140 .415 .157 .015 .140 .140 .075 .075 .062 .375 .030 min. top view side view bottom view .625 om7632nm v in 2.2 f 1 f * v out 32 1 om7632nm v in v out 2.2 f r1 * i q 32 1 pin 1: ground pin 2: out pin 3 : in downloaded from: http:///
