µA78Mxx Positive-Voltage Regulators
1 Features
3 Description
•
•
•
•
•
•
•
This series of fixed-voltage integrated-circuit voltage
regulators is designed for a wide range of
applications. The 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 500 mA of
output current. The internal current-limiting 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 as the power-pass element in precision
regulators.

8 Detailed Description
8.1 Overview
This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. The
applications include on-card regulation for elimination of noise and distribution problems associated with singlepoint regulation. Each of these regulators can deliver up to 500 mA of output current. The internal current-limiting
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 as the power-pass element in precision regulators.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. 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

OUTPUT

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

10 Power Supply Recommendations
See Recommended Operating Conditions for the recommended power supply voltages for each variation of the
UA78Mxx. Different orderable part numbers will be able to tolerate different levels of voltage. It is also
recommended to have a decoupling capacitor on the output to limit noise on the input.
11 Layout
11.1 Layout Guidelines
Keep trace widths large enough to eliminate problematic I×R voltage drops at the input and output terminals.
Input decoupling capacitors should be placed as close to the UA78MXX as possible.
