Product Description

The R1114Q311B-TR-FE IC is a member of the R1114 series voltage detector integrated with an FE package LDO regulator, designed for precision power management in low-voltage applications. This device operates within a wide voltage range of 1.8 V to 6.0 V, supporting a single input and output channel with a fixed 3.1 V output. It integrates a voltage detection circuit with adjustable hysteresis, ensuring stable operation across industrial temperature ranges (-40°C to +85°C). The compact FE package enables direct integration into space-constrained systems, commonly used in automotive electronics, IoT devices, and industrial control modules. Key advantages include ultra-low quiescent current (0.8 μA typical), high accuracy (±1.5% detection voltage), and short-circuit protection. Limited output current capacity (150 mA max) may restrict high-power applications. The IC features no built-in communication interfaces but supports cascading with external monitoring circuits for enhanced system safety.
