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
