These devices are capable of operating with input voltages from -10V to -2.7V, and support outputs from -10V to -1.2V. 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 (65dB at 1kHz) and low noise (60VRMS) make the TPS723xx ideal for low-noise applications. 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 -40C to +125C.

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.

It is offered in trimmed output voltages between -1.5V and -5.2V and as an adjustable regulator from -1.2V to -10V. It features very low noise and high power-supply rejection ratio (PSRR), making it ideal for high-sensitivity analog and RF applications. A shutdown mode is available, reducing ground current to 2A maximum over temperature and process. The TPS723xx is offered in a small SOT23 package and is specified over a -40C to +125C junction temperature range. ENABLE used for stable operation. Both the capacitor value and ESR affect stability, output noise, PSRR, and transient response. For typical applications, a 2.2F ceramic output capacitor located close to the regulator is sufficient. OUTPUT NOISE Without external bypassing, output noise of the TPS723xx from 10Hz to 100kHz is 200VRMS typical. The dominant contributor to output noise is the internal bandgap reference. Adding an external 0.01F capacitor to ground reduces noise to 60VRMS. Best noise performance is achieved using appropriate low ESR capacitors for bypassing noise at the NR and OUT pins. See Figure 21 in the Typical Characteristics section. 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 into shutdown mode, drawing 2A maximum ground current. POWER-SUPPLY REJECTION ADJUSTABLE VOLTAGE APPLICATIONS CURRENT LIMIT The TPS72301 allows designers to specify any output voltage from -10V to -1.2V. As shown in the application circuit in Figure 27, an external resistor divider is used to scale the output voltage (VOUT) to the reference voltage. For best accuracy, use precision resistors for R1 and R2. Use the equations in Figure 27 to determine the values for the resistor divider. The TPS723xx 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 9 in the Typical Characteristics section. VOUT = -1.186 1 + R1 R2 R1+R2 100k 2 5 IN OUT The TPS723xx 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. 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. THERMAL PROTECTION R1 4 3 FB EN GND R2 1 Figure 27. TPS72301 Adjustable LDO Regulator Programming CAPACITOR SELECTION FOR STABILITY As protection from damage due to excessive junction temperatures, the TPS723xx has internal protection circuitry. When junction temperature reaches approximately +165C, the output device is turned off. After the device has cooled by about 20C, the output device is enabled, allowing normal operation. For reliable operation, design is for worst-case junction temperature of +125C taking into account worst-case ambient temperature and load conditions. Appropriate input and output capacitors should be used for the intended application.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic."
