Description
The IL2596 series of regulators are monolithic integrated circuits that provide all the active functions for a
step-down 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.
The IL2596 series operates at a switching frequency of 150kHz. Available in standard 5-lead TO-220
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 100µA standby current. Self protection features include a two stage frequency reducing current limit
for output switch and an over temperature shutdown for complete protection under fault conditions. The over
temperature shutdown level is about 145^oC with 5^oC hysteresis.
