AZ1117I
LOW DROPOUT LINEAR REGULATOR WITH INDUSTRIAL TEMPERATURE RANGE
Description
Pin Assignments
The AZ1117I is available in industrial temperature range low dropout
three-terminal regulator.
The AZ1117I is 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.
VOUT
The AZ1117I 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 AZ1117I is available in the industry-standard SOT223 and
TO252-2 power packages.
Features
Current Limit: 1.35A (Typ)
Output Noise from 10Hz to 10KHz: 0.003% of VOUT
PSRR at IOUT = 300mA and f = 120Hz: 70dB
Output Voltage Accuracy: ±1% (Except 1.2V Version)
On-chip Thermal Shutdown
Maximum Quiescent Current: IQMAX = 6mA
Compatible with Low ESR Ceramic Capacitor
Operation Junction Temperature: -40°C to +125°C

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.
