FEATURES  
DESCRIPTION  
The LM2595 series of regulators are monolithic  
integrated circuits that provide all the active functions  
for a step-down (buck) switching regulator, capable of  
driving a 1A 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.

•
3.3V, 5V, 12V, and Adjustable Output Versions  
•
•
Adjustable Version Output Voltage Range,  
1.2V to 37V ±4% Max Over Line and Load  
Conditions  
Available in TO-220 and TO-263 (Surface  
Mount) Packages  
•
•
•
•
Ensured 1A Output Load Current  
Input Voltage Range Up to 40V  
Requiring  
a
minimum number of external  
components, these regulators are simple to use and  
include internal frequency compensation†, and a  
fixed-frequency oscillator.  
Requires Only 4 External Components  
Excellent Line and Load Regulation  
Specifications  
The LM2595 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. Typically, for output voltages  
less than 12V, and ambient temperatures less than  
50°C, no heat sink is required.  
Low Power Standby Mode, IQ Typically 85 μA  
High Efficiency  
Uses Readily Available Standard Inductors  
Thermal Shutdown and Current Limit  
Protection  
A standard series of inductors are available from  
several different manufacturers optimized for use with  
the LM2595 series. This feature greatly simplifies the  
design of switch-mode power supplies.  
APPLICATIONS  
•
Simple High-Efficiency Step-Down (Buck)  
Regulator  
Other features include an ensured ±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 85 μA stand-by 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.
