TPS72301DBVR

The TPS723 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 –10 V to –2.7 V,
and support outputs from –10 V to –1.2 V. This
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 (65 dB at
1 kHz) and low noise (60 μVRMS) make the TPS723
ideal for low-noise applications.
The TPS723 uses a precision voltage reference to
achieve 2% overall accuracy over load, line, and
temperature variations. Available in a small SOT23-5
package, the TPS723 is fully specified over a
temperature range of –40°C to 125°C.
