Figure 1. Package Type of AZ1117B

General Description

The AZ1117B is a low dropout three-terminal regula-

tor.

The AZ1117B has been optimized for low voltage

where transient response and minimum input voltage

are critical. It provides current limit and thermal shut-

down. Its circuit includes a trimmed bandgap reference

to assure output voltage accuracy to be within ±1%.

On-chip thermal shutdown provides protection against

a combination of high current and ambient temperature

that would create excessive junction temperature.

The AZ1117B is available in 1.2V, 1.5V, 1.8V, 2.5V,

3.3V, 5.0V fixed output voltage vesions and ADJ out-

put voltage version. The fixed versions integrate the

adjust resistors. It is also available in an adjustable ver-

sion which can set the output voltage with two external

resistors.

The AZ1117B is available in the industry-standard TO-

252-2 (1), TO-252-2 (2), TO-252-2 (3), SOT-223 and

SOT-89 power packages.
