WT1117A of positive adjustable and fixed regulators is designed to provide 1.0A output with

low dropout voltage performance. On-chip trimming adjusts the reference voltage to 1.5%.

For usage on working in post regulators or microprocessor power supplies, low voltage

operation and fast transient response are required.

WT1117A is available in surface-mount SOT-223 and TO-252 packages.
