AZ1117I LOW DROPOUT LINEAR REGULATOR WITH INDUSTRIAL TEMPERATURE RANGE Description Pin Assignments (Top View) The AZ1117I is available in industrial temperature range low dropout three-terminal regulator. 3 INPUT The AZ1117I is optimized for low voltage where transient response and minimum input voltage are critical. It provides current limit and 2 OUTPUT VOUT thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1%. On-chip thermal ADJ/GND 1 shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction SOT223 temperature. (Top View) 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 3 INPUT versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external 2 OUTPUT resistors. 1 ADJ/GND The AZ1117I is available in the industry-standard SOT223 and TO252-2 power packages. TO252-2 Features Applications Current Limit: 1.35A (Typ) Output Noise from 10Hz to 10KHz: 0.003% of V OUT USB Device PSRR at I = 300mA and f = 120Hz: 70dB OUT Add-on Card Output Voltage Accuracy: 1% (Except 1.2V Version) DVD Player On-chip Thermal Shutdown PC Motherboard Maximum Quiescent Current: I = 6mA QMAX Compatible with Low ESR Ceramic Capacitor Operation Junction Temperature: -40C to +125C Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
