DESCRIPTION  
The TPS723xx-Q1 family of 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. 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 (65 dB at 1kHz) and low  
noise (60μVRMS) make the TPS723xx-Q1 ideal for  
low-noise applications.

Thermal and Over-Current Protection  
SOT23-5 (DBV) Package  
Operating Junction Temperature Range: –40°C  
to 125°C  
The TPS723xx-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 TPS723xx-Q1 is fully specified over a  
temperature range of –40°C to +125°C.
