PMIC Voltage Reference products have become increasingly prevalent in the manufacture of digital electronics. The AP431SAN1TR-G1 is a specialized PMIC Voltage Reference with a unique power supply design that features built-in voltage conversion for varying power source strength. This device simplifies the power sourcing process, eliminating the need for multiple components to provide power for your device, saving space and cost.

The AP431SAN1TR-G1 is an adjustable PMIC voltage reference with a maximum output voltage of 3.3 V. It has a resolution of 0.625 mV and a temperature range of -40° C to +85° C. It is offered in a 5-lead, miniature SOT-23 package, allowing for very small packages in order to reduce board size and costs. It is well-suited for advanced power management solutions ranging from mobile computing, telecommunications, motor control, and metering to converting the input voltage from various power sources such as generators, batteries, and wall outlets.

The AP431SAN1TR-G1 is designed to create a steady and reliable output voltage from any unstable input voltage. Its low voltage feedback makes it suitable for low-voltage applications and its temperature compensated operation helps maintain a stable output voltage across a wide range of temperature. It has a low noise feature that helps eliminate fluctuating outputs due to possible noise generated in the system. Its internal current limit protection helps maintain a steady output voltage even under heavy load.

The AP431SAN1TR-G1 uses a two-level architecture with one bandgap reference, two DACs, and two comparators. The reference bandgap voltage is created by generating a voltage differential between two tightly matched transistors. The one bandgap reference is then buffered using a current source to reduce temperature dependent variations. The two DACs provide voltage scaling and the two comparators provide a reference voltage for the voltage conversion. The AP431SAN1TR-G1 features an output stage that includes an enable/disable circuit for further power savings.

The AP431SAN1TR-G1 has a high accuracy and low component count, making it perfect for applications where precision and cost savings without sacrificing performance and reliability is critical, such as in metering, telecommunication and power supplies for various electronic products. The device works with a wide input range and generates a steady output voltage within its temperature limit, when programmed properly, making it ideal for modern product designs.
