The L7800 series of three-terminal positive regulators is available in TO-220 TO-220FP TO-3 and D 2 
PAK packages and several fixed output voltages, making it useful in a wide range of applications. 
These regulators can provide local on-card regulation, eliminating the distribution problems associated 
with single point regulation. Each type employs internal current limiting, thermal shutdown and safe 
area protection, making it essentially indestructible. If adequate heat sinking is provided, they can 
deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices 
can be used with external components to obtain adjustable voltages and currents. 

Output Current Up To 1.5 A 
Output Voltages of 5; 5.2; 6; 8; 8.5; 9; 12; 15; 18; 24V

The AT24C01A/02/04/08/16 provides 1024/2048/4096/8192/16384 bits of serial electrically erasable 
and programmable read-only memory (EEPROM) organized as 128/256/512/1024/2048 words of 8 bits 
each. The device is optimized for use in many industrial and commercial applications where low-power 
and low-voltage operation are essential. The AT24C01A/02/04/08/16 is available in space-saving 8-pin 
PDIP, (AT24C01A/02/04/08/16), 8-lead TSSOP (AT24C01A/02/04/08/16) and 8-lead JEDEC SOIC 
(AT24C01A/02/04/08/16) packages and is accessed via a 2-wire serial interface. In addition, the entire 
family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V), 2.5V (2.5V to 5.5V) and 1.8V (1.8V to 
5.5V) versions.
