3 Description
The TPS723xx family of low-dropout (LDO) negative
voltage regulators offers an ideal combination of
features to support low noise applications. These
devices are capable of operating with input voltages
from –10 V to –2.7 V, and support outputs from –10 V
to –1.2 V. These regulators are 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 μV_RMS) make the TPS723xx
ideal for low-noise applications.
The TPS723xx uses a precision voltage reference to
achieve 2% overall accuracy over load, line, and
temperature variations. Available in a small SOT23-5
package, the TPS723xx family is fully specified over
a temperature range of –40°C to 125°C.
