AE2596
General Description
The AE2596 series of regulators are monolithic integrated circuits that provide all the active
functions for a step-down(buck) switching regulator, capable of driving a 3A load with excellent
line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V,
and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use
and include internal frequency compensation, and a fixed frequency oscillator.
The AE2596 series operates at a switching frequency of 150 kHz thus allowing smaller sized
filter components than what would be needed with lower frequency switching regulators. Available
in a standard 5-lead TO-220 package with several different lead bend options, and a 5-lead
TO-263 surface mount package.
Other features include a guaranteed±4% tolerance on output voltage under specified input
voltage and output load conditions, and±15% on the oscillator frequency. External shutdown is
included, featuring typically 80µA standby current. Self-protection features include a two stage
frequency reducing current limit for the output switch and an over temperature shutdown for
complete protection under fault conditions.
