TLV4051R5DBVR

TLV4051R5DBVR Description

The TLV4051R5DBVR from Texas Instruments is a high-performance, single-channel comparator with an integrated voltage reference, designed for precision applications in low-power systems. Operating within a 1.6V to 5.5V supply range, this device delivers exceptional efficiency with a quiescent current of just 3.5µA (max), making it ideal for battery-powered and energy-sensitive designs. Packaged in a compact SOT23-5 form factor, it combines minimal footprint with robust performance, featuring a 50mA output current (typ @ 5V) and a fast 360ns propagation delay (max). Its 20mV hysteresis ensures stable operation in noisy environments, while the ultra-low 10pA input bias current (max @ 5V) enhances accuracy in high-impedance circuits.
