LTC1727ES8-2.5#TRPBF - Voltage Regulator IC

The LTC1727ES8-2.5#TRPBF is a precision, triple supply monitor and microprocessor supervisory circuit designed by Linear Technology, which is now part of Analog Devices. This high-performance IC is specifically engineered to maintain system integrity through monitoring power supplies in digital systems. It ensures that the microprocessor and other critical system components operate reliably within their voltage thresholds.

This voltage regulator features a fixed 2.5V trip threshold for its reset output, which is designed to monitor the core voltage in a variety of systems. The device's reset output remains asserted until the monitored voltage exceeds the preset threshold and an internal timer has expired, providing a stable system reset for proper microprocessor rebooting. The LTC1727ES8-2.5#TRPBF offers a precise monitoring solution with tight threshold accuracy and reset timeout period.

The LTC1727ES8-2.5#TRPBF also includes two additional voltage monitor inputs, which can be programmed by the user for monitoring 5V, 3.3V, 2.5V, or adjustable thresholds. This versatility allows for the monitoring of multiple supply voltages in a system with a single IC, thereby reducing component count and enhancing system reliability.

Packaged in an 8-lead SOIC package, the LTC1727ES8-2.5#TRPBF is designed for surface-mount technology, making it suitable for compact and high-density circuit boards. The device is also characterized for operation from -40°C to 85°C, ensuring reliable performance in a wide range of environments and applications.

Key features of the LTC1727ES8-2.5#TRPBF include low supply current, which is essential for power-sensitive applications, and a reset active on power-up feature that provides a guaranteed system reset from power on. The device's outputs are push-pull, which eliminates the need for external pull-up resistors, further simplifying design and reducing system costs.

In summary, the LTC1727ES8-2.5#TRPBF from Linear Technology is a robust and reliable solution for system voltage monitoring and microprocessor supervision, ensuring that electronic systems operate within their specified voltage ranges for optimum performance and stability.
