FEATURES
DESCRIPTION
This series of fixed-voltage integrated-circuit voltage
• 3-Terminal Regulators
regulators is designed for a wide range of
• Output Current up to 100 mA
applications. These applications include on-card
• No External Components
regulation for elimination of noise and distribution
problems associated with single-point regulation. In
• Internal Thermal-Overload Protection
addition, they can be used with power-pass elements
• Internal Short-Circuit Current Limiting
to make high-current voltage regulators. One of these
regulators can deliver up to 100 mA of output current.
The internal limiting and thermal-shutdown features of
these regulators essentially make them immune to
overload. When used as a replacement for a Zener
diode-resistor combination, an effective improvement
in output impedance can be obtained, together with
lower bias current.
The μA78L00C and μA78L00AC series devices are
characterized for operation over the virtual junction
temperature range of 0°C to 125°C. The μA78L05AI
device is characterized for operation over the virtual
junction temperature range of −40°C to 125°C.

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.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
