TDA3663/N1,135 Integrated Circuits (ICs)

The TDA3663/N1,135 is a linear voltage regulator designed and manufactured by STMicroelectronics Corporation. It is a monolithic integrated voltage regulator for the application of precision voltage regulation, current limiting and over temperature protection. The regulator is designed to provide a regulated output voltage of 1.35 V with a maximum output current of 1 A. This device is most suitable for applications such as power supplies and portable electronic devices.

The TDA3663/N1,135 is an optimized three-terminal regulator designed to be employed as a low-noise and very reliable output voltage source. This voltage regulator features fast transient response, precise output voltage accuracy and temperature stability. The TDA3663/N1,135 has an operating input voltage range of 4.5V to 18V and a quiescent current of less than 10 μA.

The TDA3663/N1,135 is a two-stage regulator, which includes a combination of a low-power linear regulator and a high-power linear regulator. The low-power linear regulator is composed of two N-channel MOSFETs, which act as a series pass elements. This regulator maintains the output voltage in its steady state. The high power linear regulator is composed of a P-channel MOSFET, usually referred to as a high-side MOSFET, which acts as a series pass element. The regulator monitors the input voltage and adjusts output current linearly to maintain the output voltage.

The TDA3663/N1,135 also features current limit protection, over temperature protection and thermal shutdown protection. The current limit protection monitors the output current and reduces it to a safe level when the output current exceeds the threshold. The over temperature protection limits the maximum output current and reduces it below the specified threshold. If the output voltage rises above a certain limit, the thermal shutdown protection shuts down the output. All the protection features of the TDA3663/N1,135 are independent of the input voltage and the output voltage.

The TDA3663/N1,135 is used in applications such as AC-DC power supply, distributed power system, high current regulated converters, automotive electronics and industrial converters. The device can be used in applications with stringent regulation requirements such as high frequency converters, battery packs and high current voltage regulators. The device is also suitable for use in applications with noise sensitive load such as digital audio players, disc players and audio amplifier.

The TDA3663/N1,135 features fast transient response, excellent line and load regulation, low dropout voltage, low quiescent current and high accuracy. Additionally, it offers high power efficiency and low output voltage ripple. These features make it a suitable choice for applications that require precise and reliable voltage regulation.

In summary, the TDA3663/N1,135 is a linear voltage regulator designed by STMicroelectronics Corporation for providing accurate output voltage to applications such as power supplies, portable electronic devices and automotive electronics. The device features fast transient response, precise output voltage accuracy and temperature stability. It also provides current limit protection, over temperature protection and thermal shutdown protection. Its fast transient response, excellent line and load regulation, low dropout voltage, low quiescent current and high accuracy make it an ideal solution for applications that require precise and reliable voltage regulation.
