Overview
The TPS715A33DRVT is a low-dropout (LDO) linear voltage regulator produced by Texas Instruments. This device is designed to offer low quiescent current and low-power operation in compact packaging, making it ideal for battery-powered applications and as a power-management attachment to low-power microcontrollers. The TPS715A33DRVT features a fixed output voltage of 3.3V, which is suitable for powering sensitive analog and digital circuits that require a stable and precise voltage supply.
The regulator operates over a wide input voltage range of 2.5V to 24V and provides an output current of up to 80 mA. Its low dropout voltage and low quiescent current of 3.2 μA make it efficient for applications where power conservation is crucial.
