LX8941 THE INFINITE POWER OF INNOVATION The LX8941 is an adjustable, low dropout regulator rated for more than 1A of output current. It can regulate with as low as 0.8V headroom between the input and output voltages, at 1A output current, thus minimizing power dissipation. In addition, it can be used in applications where worst case supplies require a low input output differential to maintain regulation. This feature makes it ideal for some processor applications that require 4V operation from a 5V supply. In addition, the LX8941 provides an on/off switch that reduces the IC quiescent current when activated, making it ideal for battery operated applications. 2% Internally Trimmed Output Current In Excess of 1A Input-Output Differential Less Than 0.8V 1A Short Circuit Protection Internal Thermal Overload Protection Available in 5-Lead Plastic TO- 220 & Surface-Mount TO-263 IMPORTANT For the most current data, consult MICROSEMI’s website: R1 412 R2 187 VADJ R1 R2 IADJ TA °C 0 to 70 Plastic TO-220 Plastic TO-263 P 5-Pin DD 5-Pin LX8941CP LX8941CDD Note Available in Tape & Reel.
