The ZLDO1117G50TA is a low dropout positive adjustable/Fixed-mode Regulator with 1A output current capability. It has a 2% tolerance across the industrial temperature range and is guaranteed to have lower than 1.2V dropout at full load current making it ideal to provide well-regulated outputs of 1.2V to 5V with input supply voltages up to 18V. It is ideally suited to provide well-regulated supplies for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply across the whole industrial temperature range.
