General Description
Features
The AZ1117B is a low dropout three-terminal regulator with a dropout of 1.2V at 800mA output current.
·
The AZ1117B 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.
·
·
Low Dropout Voltage: 1.2V at 800mA Output
Current
Output Noise from 10Hz to 10KHz: 0.003%
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 105oC
Applications
The AZ1117B is available in 1.8V, 2.5V and 3.3V versions. 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.
