H7808AM H7808BM
Low Current Positive Voltage Regulator Of Surface Mount Device
Description
The H7808_M series of surface mount device regulators are easyto-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 7808_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. * Wide Range Of Available, Fixed Output Voltages * Internal Short-Circuit Current Limiting * Internal Thermal Overload Protection * No External Components Required

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 H7808AM, H7808BM
