SLVS346C – SEPTEMBER 2003 – REVISED SEPTEMBER 2014 TPS723xx 200mA Low-Noise, High-PSRR
Negative Output Low-Dropout Linear Regulators
1 Features 1 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, lowcost 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 ОјVRMS) make the TPS723xx
ideal for low-noise applications. Ultralow Noise: 60 ОјVRMS Typical
High PSRR: 65 dB Typical at 1 kHz
Low Dropout Voltage: 280 mV Typical at 200 mA,
2.5 V …
