These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. Each of these regulators can deliver up to 1.5 A of output current. The internal currentlimiting and thermal-shutdown features of these regulators essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents, and also can be used as the power-pass element in precision regulators. 8.2 Functional Schematic INPUT OUTPUT COMMON 8.3 Feature Description 8.3.1 Thermal Overload When the die temperature increases to unwanted levels, the device will reduce the output current to lower its temperature. Under heavy loads, the device may alternate between on and off output states to regulate temperature. 8.3.2 Short-Circuit Current Limiting In the event of a short circuit, the device will limit its own current to safe levels by lowering the bias voltage of internal pass transistors. If the device becomes overheated, the thermal overload protection will take over. 8.4 Device Functional Modes 8.4.1 Fixed-Output Mode These devices are available in fixed-output voltages. See the orderable part list for the desired output.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The following section shows application details of the µA78xx as a linear regulator. 9.2 Typical Application +V +VO µA78xx 0.33 µF 0.1 µF Figure 2. Fixed-Output Regulator 9.2.1 Design Requirements • Input supply capacitor recommended for filtering noise on the input • Output supply decoupling capacitor for stabilizing the output 9.2.2 Detailed Design Procedure 9.2.2.1 Operation With a Load Common to a Voltage of Opposite Polarity In many cases, a regulator powers a load that is not connected to ground but, instead, is connected to a voltage source of opposite polarity (e.g., operational amplifiers, level-shifting circuits, etc.). In these cases, a clamp diode should be connected to the regulator output as shown in Figure 3. This protects the regulator from output polarity reversals during startup and short-circuit operation. +VI +VO µA78xx 1N4001 or Equivalent −VO Figure 3. Output Polarity-Reversal-Protection Circuit 9.2.2.2 Reverse-Bias Protection Occasionally, the input voltage to the regulator can collapse faster than the output voltage. This can occur, for example, when the input supply is crowbarred during an output overvoltage condition. If the output voltage is greater than approximately 7 V, the emitter-base junction of the series-pass element (internal or external) could break down and be damaged. To prevent this, a diode shunt can be used as shown in Figure 4. 12 Submit Documentation Feedback Copyright © 1976–2015, Texas Instruments Incorporated Product Folder Links: uA7805 uA7808 uA7810 uA7812 uA7815 uA7824 uA7805, uA7808, uA7810 uA7812, uA7815, uA7824 www.ti.com SLVS056P – MAY 1976 – REVISED JANUARY 2015 Typical Application (continued) VI +VO µA78xx Figure 4.

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) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
