The TPS7A33 series of linear regulators are negative voltage
(36 V), ultralow-noise (16-µVRMS, 72-dB PSRR) linear regulators capable of
sourcing a maximum load of 1 A.
The TPS7A33 series include a complementary metal oxide semiconductor (CMOS)
logic-level-compatible enable pin (EN) to allow for user-customizable power management schemes.
Other features available include built-in current limit and thermal shutdown features to protect
the device and system during fault conditions.
The TPS7A33 family is designed using bipolar technology primarily for high-accuracy,
high-precision instrumentation applications, where clean voltage rails are critical to maximize
system performance. This feature makes it ideal to power operational amplifiers, analog-to-digital
converters (ADCs), digital-to-analog converters (DACs), and other high-performance analog
In addition, the TPS7A33 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 ensured in sensitive instrumentation, medical, test and measurement,
audio, and RF applications.
applications where positive and negative high-performance rails are required, consider the
TPS7A4700 positive high-voltage,
ultralow-noise, low-dropout linear regulator as well.
