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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION
DEVICE OPERATION
POWER-SUPPLY REJECTION
The TPS723xx-Q1 is a low-dropout negative linear
voltage regulator with a rated current of 200mA. It
features very low noise and high power-supply
rejection ratio (PSRR), making it ideal for
The TPS723xx-Q1 offers a very high PSRR for
applications with noisy input sources or highly
sensitive output supply lines. For best PSRR, use
high-quality input and output capacitors.
high-sensitivity analog and RF applications.
A
shutdown mode is available, reducing ground current
to 2μA maximum over temperature and process. The
TPS723xx-Q1 is offered in a small SOT23 package
and is specified over a –40°C to +125°C junction
temperature range.
CURRENT LIMIT
The TPS723xx-Q1 has internal circuitry that monitors
and limits output current to protect the regulator from
damage under all load conditions. When output
current reaches the output current limit (550mA
typical), protection circuitry turns on, reducing output
voltage to ensure that current does not increase. See
Figure 8 in the Typical Characteristics section.
ENABLE
The enable pin is active above +1.5V and
below –1.5V, allowing it to be controlled by a
standard TTL signal or by connection to VI if not
used. When driven to GND most internal circuitry is
turned off, putting the TPS723xx-Q1 into shutdown
mode, drawing 2μA maximum ground current.
Do not drive the output more than 0.3V above the
input. Doing so will bias the body diode in the pass
FET, allowing current to flow from the output to the
input. This current is not limited by the device. If this
condition is expected, care should be taken to
externally limit the reverse current.
CAPACITOR SELECTION FOR STABILITY
Appropriate input and output capacitors should be
used for the intended application. The TPS723xx-Q1
only requires a 2.2μF ceramic output capacitor to be
used for stable operation. Both the capacitor value
and ESR affect stability, output noise, PSRR, and
transient response. For typical applications, a 2.2μF
ceramic output capacitor located close to the
regulator is sufficient.
THERMAL PROTECTION
As protection from damage due to excessive junction
temperatures, the TPS723xx-Q1 has internal
protection circuitry. When junction temperature
reaches approximately +165°C, the output device is
turned off. After the device has cooled by about 20°C,
the output device is enabled, allowing normal
operation. For reliable operation, design is for
worst-case junction temperature of ≤ +125°C taking
into account worst-case ambient temperature and
load conditions.
OUTPUT NOISE
Without external bypassing, output noise of the
TPS723xx-Q1 from 10Hz to 100kHz is 200μVRMS
typical. The dominant contributor to output noise is
the internal bandgap reference. Adding an external
0.01μF capacitor to ground reduces noise to
60μVRMS. Best noise performance is achieved using
appropriate low ESR capacitors for bypassing noise
at the NR and OUT pins. See Figure 18 in the Typical
Characteristics section.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
