LP3470M5-4.38/NOPB TI Supervisory Circuit | SOT-23-5 | 4.38V Threshold, Active-Low Reset

Product Overview

The LP3470M5-4.38/NOPB is a low-power supervisory circuit from Texas Instruments (TI) designed to monitor power supply voltages in digital systems. It provides a reset output during power-up, power-down, and brownout conditions. The device features a fixed threshold voltage of 4.38V, making it ideal for 5V systems. Housed in a compact SOT-23-5 package, it offers a combination of low quiescent current (typically 16 µA) and high accuracy (±2% over temperature). The open-drain RESET output remains asserted for a minimum of 140 ms after VCC rises above the threshold, ensuring proper system initialization.
