PL78L09XM3
SOT-89
Description
The PL78L09XM3 series of surface mount regulators are easy-to-use devices suitable for
multitude of applications that require a regulated supply of up to 100mA. These regulators feature
internal current limiting and thermal shutdown, making them remarkably rugged. No external
components are required with the PL78L09XM3 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:
•
Wide Range Of Available, Fixed Output Voltages
•
Internal Short-Circuit Current Limiting
•
Internal Thermal Overload Protection

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.
Note : C1 and C2 are required if regulator is located
far from power supply filter and load, or oscillation
may induced on the loop.
