Description

The TDA7388 is an integrated audio amplifier IC manufactured by STMicroelectronics. It is a four-channel audio amplifier designed for use in car audio systems, and is capable of delivering up to 45W of output power per channel. This IC has a low noise level, high efficiency, and is capable of driving high-impedance loads. It also features a mute function, thermal protection, and a low-power standby mode.

The TDA7388 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed
for high end car radio applications.

Based on a fully complementary PNP/NPN configuration, the TDA7388 allows a rail to rail
output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary
components count allows very compact sets.

78L05 voltage regulator

 

Description

The 78L05 is a voltage regulator integrated circuit (IC) commonly used in electronics projects. It is a type of voltage regulator that provides a constant voltage output of 5 volts and is commonly used to power small electronic devices, such as microcontrollers, sensors, and displays

The 78L05 series of three-terminal positive regulators employ internal current limiting and hermal shutdown, making them essentially ndestructible. If adequate heat-sink is provided, they can deliver up to 100 mA output current. They are intended as fixed voltage regulators in a wide range of applications including local or on card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power pass elements to make high-current voltage regulators. The voltage regulator series used as Zener diode/resistor combination replacement, offers e improvement along with lower quiescent current and lower noise.
