HI-SINCERITY Spec. No. : Preliminary Data Issued Date : 1998.08.01 Revised Date : 2001.01.30 Page No. : 1/3 MICROELECTRONICS CORP. H7812AM H7812BM Low Current Positive Voltage Regulator Of Surface Mount Device Description The H7812_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 7812_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 Absolute Maximum Ratings (Ta=25°C) • Input Voltage................................................... 30 V (5V Through 9V), 35 V (12V Through 18V) • Total Power Dissipation ...........................................................................................

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 H7812AM, H7812BM 2.84K GND HSMC Product Specification HI-SINCERITY Spec.
