TDA8137

TDA8137 DUAL 5.1V REGULATOR WITH DISABLE AND RESET . . . . . . . OUTPUT CURRENTS UP TO 1A FIXED PRECISION OUTPUT VOLTAGES 5.1V ± 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 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.
