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
