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 80 µA standby current. Selfprotection features
include a two stage frequency reducing current limit for
the output switch and an over temperature shutdown for
complete protection under fault conditions.

Note 3: Typical numbers are at 25 and represent the most likely norm.
Note4: All limits guaranteed at room temperature (standard type face) and at t emperature
extremes (bold type face). All room temperature limits are 100% production tested. All
limits at temperature extremes are guaranteed via correlation using standard Statistical
Quality Control (SQC) methods. All limits are used to calculate Average Outgoing
Quality Level (AOQL).
Note5: External components such as the catch diode, inductor, input and output capacitors, and
voltage programming resistors can affect switching regulator system performance.
Note6: The switching frequency is reduced when the second stage current limit is activated.
Note7: No diode, inductor or capacitor connected to output pin.
Note8: Feedback pin removed from output and connected to 0V to force the output transistor
switch ON.
Note9: Feedback pin removed from output and connected to 12V for the 3.3V, 5V, and the ADJ.
version, and 15V for the 12V version, to force the output transistor switch OFF.
Note10: VIN = 40V.
Note11: Junction to ambient thermal resistance (no external heat sink) for the TO-220 package
mounted vertically, with the leads soldered to a printed circuit board with (1 oz.)copper
area of approximately 1 in2.
