The TPS7A49 series of devices are positive, high- voltage (36 V),
ultralow-noise (15.4 μVRMS, 72-dB PSRR) linear regulators that can
source a 150-mA load.
These linear regulators include a CMOS logic-level- compatible
enable pin and capacitor-programmable soft-start function that
allows for customized power- management schemes. Other available
features include built-in current limit and thermal shutdown
protection to safeguard the device and system during fault
conditions.
The TPS7A49 family is designed using bipolar technology, and is
ideal for high-accuracy, high- precision instrumentation
applications where clean voltage rails are critical to maximize
system performance. This design makes the device an excellent
choice to power operational amplifiers, analog-to-digital
converters (ADCs), digital-to-analog converters (DACs), and other
high-performance analog circuitry.
In addition, the TPS7A49 family of linear regulators is suitable
for post dc-dc converter regulation. By filtering out the output
voltage ripple inherent to dc-dc switching conversion, maximum
system performance is provided in sensitive instrumentation, test
and measurement, audio, and RF applications.
For applications where positive and negative high- performance
rails are required, consider TI’s TPS7A30xx family of negative
high-voltage, ultralow- noise linear regulators as well.
