ZLDO1117
1A LOW DROPOUT POSITIVE REGULATOR
1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V AND ADJUSTABLE OUTPUTS
Description
ZLDO1117 is a low dropout positive adjustable or fixed-mode
regulator with 1A output current capability.
Pin Assignments
SOT223
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.
