ZLDO1117

1A Low Dropout Positive Regulator

1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V and Adjustable outputs

Description

Pin Assignments

SOT223

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.
