Introduction

AS1364-BTDT-30-1K is a linear voltage regulator (PMIC) manufactured by STMicroelectronics, a leader in the power management industry. It provides a precise output voltage of 3.3 V, adjustable from 0.8 V to 15 V. This regulator offers a very high accuracy of ±2% (2.97 V to 3.63 V) and full temperature range of -40°C to +125°C.

Application Field

The AS1364-BTDT-30-1K is designed for a wide variety of applications, including embedded controllers, DSPs, and microprocessors, as well as automotive, industrial, and consumer products. It can be used in many applications that require precise power regulation such as microcontrollers, telecommunication systems, automotive equipment, computer products, video and audio equipment, etc.

The AS1364-BTDT-30-1K is ideal for use in environments that require a very low noise operation, as it operates with a very low quiescent current. The regulator is also capable of extremely fast transient response, making it well suited for RF pulse applications.

Working Principle

The AS1364-BTDT-30-1K works by controlling an N-channel MOSFET in a buck topology, which provides the feedback and regulation loop. This loop translates the output voltage to a level that can be compared to a reference voltage, which is then compared to the actual output voltage. If the output voltage deviates too far from the reference voltage, the current sourced to the load is adjusted in order to maintain the desired output voltage. This loop is repeated continually while the device is in operation, providing an accurate and stable output.

The AS1364-BTDT-30-1K is a highly integrated device that offers robust protection against short-circuits, over-current, thermal overload, and under-voltage. It is also designed to be tolerant to capacitive loading, eliminating the need for additional external components in some applications. The device also features soft-start, allowing for the output voltage to ramp up gradually for increased system stability.

Conclusion

The AS1364-BTDT-30-1K is a linear voltage regulator from STMicroelectronics, providing a precise output voltage of 3.3 V, adjustable from 0.8 V to 15 V. Its accuracy is ±2% over the full temperature range and features a very low quiescent current. Its integrated protection features make it very reliable in applications requiring stable, precise, and low noise operation, making it suitable for microcontrollers, telecommunication systems, automotive equipment, computer products, video and audio equipment, etc.
