TDA8132 5.1V +12V DISABLE VOLTAGE REGULATOR .. . .. . .. OUTPUT CURRENTS UP TO 1A FIXED PRECISION OUTPUT 1 VOLTAGE 5.1V +/- 2% FIXED PRECISION OUTPUT 2 VOLTAGE 12V +/- 2% OUTPUT 1 WITH DISABLE BY TTL INPUT OUTPUT 2 WITH DISABLE BY TTL INPUT SHORT CIRCUIT PROTECTION AT BOTH OUTPUTS THERMAL PROTECTION LOW DROP OUTPUT VOLTAGE HEPTAWATT (Plastic Package) ORDER CODE : TDA8132 DESCRIPTION The TDA8132 is a monolithic dual positive voltage regulator designedto provide fixed precision output voltages of 5.1V and 12V at currents up to 1A. Each output can be disabled separately by a TTL input. Short circuit and thermal protections are included. 7 OUTPUT1 6 OUTPUT2 5 DISABLE FOR OUTPUT 1 4 GROUND 3 DISABLE FOR OUTPUT 2 2 INPUT 2 1 INPUT 1 8132-01.EPS PIN CONNECTIONS Tab. connected to Pin 4 January 1996 1/4 TDA8132 BLOCK DIAGRAM DISABLE INPUT 1 INPUT 2 1 2 REFERENCE OUTPUT 1 7 OUTPUT 1 PROTECTION DISABLE 5 DISABLE DISABLE OUTPUT 2 6 OUTPUT 2 3 8132-02.EPS TDA8132 4 CIRCUIT DESCRIPTION The TDA8132 is a dual voltage regulator with separate Disable for each output. The two regulation parts are supplied from one voltage reference circuit trimmed by zener zap during EWS test. Since the supply voltage of this last is connected at Pin 1 (VIN1), the regulator 2 will not work if Pin 1 is not supplied. The outputs stage have been realized in darlington configuration with a drop typical 1.2V. For each output a disable circuit switches-off this output if a voltage lower than 0.8V is applied at corresponding Pin (Pin 3 for output 2, Pin 5 for output 1).
