D

Available in −2.5 V, and Adjustable  
(−1.2 V to −10 V) Versions  
The TPS723xx family of low-dropout (LDO) negative  
voltage regulators offers an ideal combination of features  
to support low noise applications. The devices are capable  
of operating with input voltages from −10 V to −2.7 V, and  
supporting 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 k Hz) and low noise (60 µVRMS) make  
the TPS723xx ideal for low-noise applications.

Thermal and Overcurrent Protection  
5-Pin SOT-23 (DBV) Package  
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.
