μA78 Series Linear Voltage Regulators, Texas Instruments


The Texas Instruments μA78 families are linear voltage regulators that cover a range of fixed output voltages from 2.6 V to 15 V.The three Terminal positive voltage regulators offer thermal overload shutdown and internal current limiting. There is no need for external components although it is possible to adjust the voltage and current with external devices. The TI positive linear regulator IC produces an output current of 1.5A for the μA78 series, 0.1A for the μA78L version and the μA78M offers 0.5A current output. It is used in a wide variety of applications including on-card regulation which eliminates problems that occur with single point regulation also suitable in telecommunications, computing and portable device applications.

Output Current: 1.5 A (μA78xx); 0.1 A (μA78Lxx) and 0.5 A (μA78Mxx)

Internal Thermal-Overload Protection, Internal Short-Circuit Current Limiting

Output Transistor Safe-Area Compensation
