applications. This device is capable of operating with
2% Overall Accuracy
input voltages from –10 V to –2.7 V. The TPS72325-
(Line, Load, Temperature)
Q1 regulator is stable with small, low-cost ceramic
capacitors, and includes enable (EN) and noise-
Thermal and Overcurrent Protection
reduction (NR) functions. Internal detection and
SOT23-5 (DBV) Package
shutdown logic provide thermal short-circuit and
Operating Junction Temperature Range: –40°C
overcurrent protection. High PSRR (65 dB at 1 kHz)
to 125°C
and low noise (60
μVRMS) make the TPS723xx-Q1
ideal for low-noise applications.
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 specification covers the
full temperature range of –40°C to 125°C.
