TECHNICAL DATA
KKA8137 DUAL 5.1V
REGULATOR WITH DISABLE AND RESET
The KKA8137 is a monolithic dual positive voltage
regulator designed to provide fixed precision output voltages of 5.1 V at currents up to 1 A. An internal reset circuit generates a reset pulse when the output 1 decreases below the regulated voltage value. Output 2 can be disabled by TTL input. Short circuit and thermal protections are included. Output currents up to 1 A Fixed precision OUTPUT voltages 5.1 V ± 2% OUTPUT 1 with RESET facility OUTPUT 2 with DISABLE by TTL input Short circuit protection at both outputs Thermal protection Low drop output voltage TO-220AB/7
