AZ1117B
The AZ1117B is a low dropout three-terminal regula-
tor.
The AZ1117B has been optimized for low voltage
where transient response and minimum input voltage
are critical. It provides current limit and thermal shut-
down. 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 AZ1117B is available in 1.2V, 1.5V, 1.8V, 2.5V,
3.3V, 5.0V fixed output voltage vesions and ADJ out-
put voltage version. The fixed versions integrate the
adjust resistors. It is also available in an adjustable ver-
sion 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
The AZ1117B is available in the industry-standard TO-
252-2 (1), TO-252-2 (2), TO-252-2 (3), SOT-223 and
SOT-89 power packages.
