TPS7A2045PDBVR TI LDO Regulator | SOT-23-5 | 200mA, 1μA IQ

Product Overview

The TPS7A2045PDBVR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for ultra-low-power applications. It delivers up to 200 mA output current with a typical dropout voltage of only 180 mV at full load. The device features a very low quiescent current of 1 μA (typical), making it ideal for battery-powered systems. It operates over an input voltage range of 1.6 V to 6.5 V and provides a fixed output voltage of 4.5 V with ±2% accuracy. The TPS7A2045PDBVR is available in a small SOT-23-5 package, enabling compact designs.
