AZ1117B

Part Obsolete 600mA LOW DROPOUT LINEAR REGULATOR LOW DROPOUT LINEAR REGULATOR Data Sheet APA1P121371M7 AZ1117B General Description Features The AZ1117B is a low dropout three-terminal regulator. The AZ1117B has been optimized for low voltage E where transient response and minimum input voltage are critical. It provides current limit and thermal shutdown. Its circuit includes a trimmed bandgap reference T 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. E The AZ1117B is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V fixed output voltage vesions and ADJ out- L put 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. · Current Limit: 1.0A (Typ.) · Output Noise from 10Hz to 10KHz: 0.003% of VOUT · PSRR at IOUT=300mA and f=120Hz: 70dB · Output Voltage Accuracy: ±1% · On-chip Thermal Shutdown · Maximum Quiescent Current: IQMAX=6mA · Operation Junction Temperature: -20 to 125oC Applications · USB Device · Add-on Card · DVD Player · PC Motherboard O The AZ1117B is available in the industry-standard OBS SOT-223 and SOT-89 power packages.
