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 UA78Mxx devices are ideal for use as linear regulators with few external components needed for a working design. They are also useful for attenuating power supply noise. 9.2 Typical Application Figure 2. Fixed-Output Regulator 9.2.1 Design Requirements An 0.33-µF decoupling capacitor on the input and a 0.1-µF decoupling capacitor on the output are recommended for the UA78Mxx to behave as close to datasheet specifications as possible. 9.2.2 Detailed Design Procedure The customer's end application will determine how the schematic for UA78Mxx is designed. For example, if there is a load connected to a negative voltage as its ground, a clamp diode may be necessary on the output. In the event of an input short circuit or another case where the output voltage can be higher than the input, a diode shunt can be connected across the device with the anode at the output and cathode at the input Copyright © 1976–2015, Texas Instruments Incorporated Submit Documentation Feedback 11 Product Folder Links: uA78M05 uA78M06 uA78M08 uA78M09 uA78M10 uA78M12 uA78M33 |
