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 145oC with 5oC hysteresis.
