13.8.LM7800 (LM7805/LM7808)
13.8.1.Description
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.
13.8.2.Features
Output Current Up To 1.5 A
Output Voltages of 5; 5.2; 6; 8; 8.5; 9; 12; 15; 18; 24V
Thermal Over load protection
Short Circuit Protection
Output Transition SOA Protection
13.9.AT24C08
13.9.1.Description
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.
