ZLDO1117
Document number: Ds32018 Rev. 4 - 2
Description
ZLDO1117 is a low dropout positive adjustable or fixed-
mode regulator with 1A output current capability.
The ZLDO1117 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 5.0V with input supply
voltages up to 18V.
The ZLDO1117 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.
