TDA8138 Monolithic Dual Positive Voltage Regulator 5.1V/12V 1A منظم جهد مزدوج

The TDA8138 Monolithic Dual Positive Voltage Regulator provides two fixed positive output rails—5.1V and 12V—with a combined design intended for compact, dual-supply applications. This regulator is supplied as a single integrated device to simplify power management where two stable positive voltages are required from a single input source.

Key characteristics include two fixed regulated outputs and rated output current up to 1A for the device as represented in the product title. The device is suited for powering mixed-voltage circuitry such as analog front-ends, logic modules, sensors, small motors, and auxiliary electronics that require both a 5.1V and a 12V supply. Using a monolithic dual regulator reduces board space, component count, and simplifies thermal and layout considerations compared to two separate regulators.

Designers should consult the manufacturer's datasheet and application notes for complete electrical specifications, recommended external components, thermal limits, pin assignments, and layout guidance before integration. Proper input decoupling, output capacitors, and heat dissipation measures should be selected according to the datasheet to ensure reliable operation in the intended application environment.
