TDA8137
TDA8137 is DUAL 5.1V REGULATOR WITH DISABLE AND RESET manufactured by STMicroelectronics.
DESCRIPTION
The TDA8137 is a monolithic dual positive voltage regulator designed to provide fixed precision output voltages of 5.1V at currents up to 1A. 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. PIN CONNECTION (top view)
