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 Standard Application Circuit
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
Ordering Information
A common ground is required between the input and the
output voltages. The input voltage must remain typically

Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as
possible, and thermal effects must be taken into account separately.
