TDA8139 5.1V AND ADJUSTABLE VOLTAGE REGULATOR WITH DISABLE AND RESET . . . . . . . . OUTPUT CURRENTS UP TO 750mA FIXED PRECISION OUTPUT 1 VOLTAGE 5.1V ± 2% OUTPUT 2 VOLTAGE PROGRAMMABLE FROM 2.8 TO 16V 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 TDA8139 is a monolithic dual positive voltage regulator designed to provide precision output voltages of 5.1V and adjustable at currents up to 750mA. An internal reset circuit generates a reset pulse when the output 1 decrease below the regulated voltage value. Output 2 can be disabled by TTL input. Short circuit and thermal protections are included.
