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.

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.
