DESCRIPTION
The TPS72325-Q1 low-dropout (LDO) negative
voltage regulator offers an ideal combination of
features to support low noise applications. This
device is capable of operating with input voltages
from –10V to –2.7V, and support outputs from –10V
to –1.2V. The TPS72325-Q1 regulator is stable with
small, low-cost ceramic capacitors, and include
enable (EN) and noise reduction (NR) functions.
Thermal short-circuit and over-current protections are
provided by internal detection and shutdown logic.
High PSRR (65dB at 1kHz) and low noise (60mVRMS)
make the TPS72325-Q1 ideal for low-noise
applications.
The TPS72325-Q1 uses a precision voltage
reference to achieve 2% overall accuracy over load,
line, and temperature variations. Available in a small
SOT23-5 package, the TPS72325-Q1 is fully
specified over a temperature range of –40°C to
+125°C.
