General Description
The TS78L00 Series of positive voltage Regulators are inexpensive, easy-to-use devices suitable for a multitude
of applications that require a regulated supply of up to 100mA. Like their higher power TS7800 and TS78M00
Series cousins, these regulators feature internal current limiting and thermal shutdown making them remarkably
rugged. No external components are required with the TS78L00 devices in many applications.
These devices offer a substantial performance advantage over the traditional zener diode-resistor combination,
as output impedance and quiescent current are substantially reduced.
Features
● Output Voltage Range 3.3 to 24V
● Output current up to 100mA
● No external components required
● Internal thermal overload protection
● Internal short-circuit current limiting
● Output transistor safe-area compensation
● Output voltage offered in 4% tolerance
Standard Application Circuit
A common ground is required between the input and the
output voltages. The input voltage must remain typically
2.0V above the output voltage even during the low point
on the Input ripple voltage.
XX = these two digits of the type number indicate
voltage.
* = Cin is required if regulator is located an appreciable
distance from power supply filter.
** = Co is not needed for stability; however, it does
improve transient response.

Application Information
Design Considerations
The TS78L00 Series of fixed voltage regulators are designed with Thermal Overload Protection that shuts down
the circuit when subjected to an excessive power overload condition. Internal Short Circuit protection Limits the
maximum current the circuit will pass.
In many low current applications, compensation capacitors are not required. However, it is recommended that the
regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long wire
lengths, or if the output load capacitance is large. The input bypass capacitor should be selected to provide good
high-frequency characteristics to insure stable operation under all load conditions. A 0.33µF or larger tantalum,
mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass
capacitor should be mounted with the shortest possible leads directly across the regulators input terminals. Good
construction techniques should be used to minimize ground loops and lead resistance drops since the regulator
has no external sense lead. Bypassing the output is also recommended.
FIGURE 1 – Current Regulator
The TS78L00 regulators can also be used as a current
source when connected as above. In order to minimize
dissipation the TS78L05 is chosen in this application.
Resistor R determines the current as follows:
I
IB
=3.8mA over lined and load changes
For example, a 100mA current source would require R to
be a 50Ω. 1/2W resistor and the output voltage compliance
would be the input voltage less 7V.
