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.

transistor lm350k

Description

LM350K of adjustable 3-terminal positive voltage regulator is capable of supplying in excess of 3A over a 1.2V to 33V output range. They are exceptionally easy to use and require only 2 external resistors to set the output voltage. Further, both line and load regulation are comparable to discrete designs. Also, the LM350 is packaged in standard transistor packages which are easily mounted and handled.

In addition to higher performance than fixed regulators, the LM350 series offers full overload protection available only in IC’s. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is accidentally disconnected.

Normally, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors in which case an input bypass is needed. An output capacitor can be added to improve transient response, while bypassing the adjustment pin will increase the regulator’s ripple rejection.
