| KA78RL00 Adjustable Micro Power Voltage Regulator • Low Quiescent Current • Low Dropout Voltage • Low Temperature Coefficient • Tight Line and Load Regulation • Guaranteed 100mA Output Current • Internal Short Current & Thermal Limit • Error Signals of Output Dropout 8 pin Versions Only • External Shut-down 8 pin Versions Only The KA78RLOO is an adjustable micro power voltage regulator suitable for use in battery-powered systems. This regulator has various functions such as alarm which warns of a low output voltage, often due to falling batteries on the input, the external shutdown which enables the regulator to be switched on and off, current and temperature limiting. 8-SOP Internal Block Diagram OUT 1 PROGRAM 2 FROM EXTERNAL INPUT SHUTDOWN 3 GROUND 4 INPUT 8 + ERROR AMPLIFIER FEEDBACK 7 OFFSE EERRRROORR CCOOMMPPAARRAATTOOR 1.25V + REFERENCE TAP 6 TO EXTERNAL ERROR 5 INPUT 2001 Fairchild Semiconductor Corporation KA78RL00 Absolute Maximum Ratings Parameter Input Supply Voltage Power Dissipation Thermal Resistance Junction-Air Storage Temperature Range Operating Junction Temperature Range Symbol VIN PD TSTG TOPR Value ~ +30 Internally Limited -65 ~ +150 -40 ~ +125 Unit V W °C/W °C °C KA78RL00 Electrical Characteristics Refer to the test circuit, Ta = 25 °C, unless otherwise specified Parameter ALL VOLTAGE OPTIONS Output Voltage Temperature Coefficient Line Regulation Note2 Load Regulation Note2 Dropout Voltage Ground Current Ordering Information Product Number KA78RL00D Package 8-SOP Operationg Temperature -40 ~ +125°C KA78RL00 KA78RL00 DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
