AZ1117C
LOW DROPOUT LINEAR REGULATOR
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 TO252-2 Series
(including TO252-2 (3), TO252-2 (4), and TO252-2 (5)), SOT89 and
SOT223 power packages.
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: -20°C to +125°C
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
Applications
USB Device
Add-on Card
DVD Player
PC Motherboard
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.
