LYT4213E2 (E2), is a product from STMicroelectronics. It is a CMOS linear voltage regulator family, offering excellent consumption and output voltage precision. Constructed using a high-precision CMOS process, the LYT4213E2 is ideal for applications requiring low noise, fast response and low power consumption. It is also capable of working with very low input-output voltage differences

The application fields of the LYT4213E2 are in PMIC (Power Management Integrated Circuit) - AC/DC converters and Offline Switchers. AC/DC converters are used in the applications related to automation, communication, automotive, consumer electronics, security and other industrial applications. The LYT4213E2 can provide a power regulation with improved efficiency, output noise and temperature stability. The high voltage range and low quiescent current of this linear regulator make it also suitable for power supplies for high power battery applications.

The working principle of the LYT4213E2 is simple. The input voltage is regulated by the series pass regulator. The error amplifier circuit generates the control of the output voltage through the main switch. The main switch is then controlled by the PWM comparator. The current ramp is generated and stored in the capacitor, can be used by the PWM comparator to adjust the speed when the output voltage is within the preset range. The output voltage is then tested against the reference voltage of the error amplifier, to ensure the stability of the circuit.

The LYT4213E2 includes many safety functions, such as over-current protection and over-temperature protection that can increase the system effectiveness and reduce the complexity of the power control. It is compatible with the I 2 C interface, allowing simple monitoring and control. The LYT4213E2 linear voltage regulator can operate 1µA over a wide temperature range ( -40°C to +125°C) with an excellent line and load regulation accuracy.

The LYT4213E2 from STMicroelectronics offers advanced CMOS process technology, improved system reliability, flexibility and cost effectiveness. It is a great choice for many PMIC applications - AC/DC converters and Offline Switchers, as it can guarantee high accuracy, low noise and fast response.
