| 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.

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 ABSOLUTE MAXIMUM RATINGS Symbol VIN VDIS IO1, 2 Pt Tstg Tj DC Input Voltage Pin 1 Disable Input Voltage Pins 3-5 Output Currents Power Dissipation Storage Temperature Junction Temperature Parameter Value 20 20 Internally Limited -65, +150 0, +150 o o 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).
