The LM3940IMP-3.3 is one member of the LM3940 family,it is designed as one kind of 1A low dropout regulator and provide 3.3V from a 5V supply.It is ideally suited for systems which contain both 5V and 3.3V logic, with prime power provided from a 5V bus.And the T0-220 package of it means that in most applicat-ions the full 1A of load current can be delivered without using an additional heatsink.
Features of the LM3940IMP-3.3 are:(1)output voltage specified over temperature;(2)excellent load regulation;(3)guaranteed 1A output current;(4)requires only one external component;(5)built-in protection against excess temperature;(6)short circuit protected.Also it can be used in laptop/desktop computers and logic systems.
The absolute maximum ratings of the LM3940IMP-3.3 can be summarized as:(1)storage temperature range:-65°C to +150°C;(2)operating junction temper-ature range:-40°C to +125°C;(3)lead temperature (soldering,5 seconds):260°C;(4)power dissipation:internally limited;(5)input supply voltage:7.5 V;(6)ESD rating:2 kV.If you want to know more information such as the electrical characteristics about the LM3940IMP-3.3,please download the datasheet in www.seekdatasheet.com or www.chinaicmart.com.
