General Description
The MAQ5283 high-performance linear regulator offers a
very-wide input operating voltage range, up to 120V DC,
and supplies an output current of up to 150mA.
The MAQ5283 is ideal for high input voltage applications
such as automotive, industrial, and telecom, because it
offers ±3% initial accuracy, extremely high power supply
rejection ratio (75dB at 10kHz) and an ultra-low quiescent
current of 8µA. The MAQ5283 is optimized for high-voltage
line transients, making it ideal for harsh environment
applications.
The MAQ5283 is offered in both fixed output voltage (3.3V
or 5.0V) and adjustable output voltage (1.23V to 5.5V)
options.
The MAQ5283 operates over a
−40°C
to +125°C
temperature range and is available in a lead-free, RoHS-
compliant, ePad SOIC-8 package.
Data sheet and support documentation are available on
the Micrel website:

Exceeding an absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation at any T
A
(ambient temperature) is P
D(max)
= (T
J(max)
– T
A
) /
θ
JA
. Exceeding the maximum allowable power
dissipation results in excessive die temperature, and causes the regulator to enter thermal shutdown.
Devices are ESD sensitive; use proper handling precautions. Human body model, 1.5kΩ in series with 100pF.

section. Actual results depend on the size of the PCB, ambient temperature, and
proximity to other heat emitting components.
