3 Description
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.
