LOW DROPOUT LINEAR REGULATOR

Description

The AZ1117C is a low dropout three-terminal regulator.

The AZ1117C has been optimized for low voltage where transient

response and minimum input voltage are critical. It provides current

limit and thermal shutdown. 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 AZ1117C is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V fixed

output voltage versions and ADJ output voltage version. The fixed

versions integrate the adjust resistors. It is also available in an

adjustable version which can set the output voltage with two external

resistors.

The AZ1117C is available in the industry-standard TO2522 (3),

TO2522 (4), and TO2522 (5), SOT89-3L and SOT223 power

packages.

Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
