H7808AM
H7808BM
Low Current Positive Voltage Regulator Of Surface Mount Device
Description
The H7808_M series of surface mount device 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 780-
8_M 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.

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
