1 / 5 page CYStech Electronics Corp. Spec. No. : C518M3 Issued Date : 2003.04.02 Revised Date :2007.11.19 Page No. : 1/5 LM78L09M3 CYStek Product Specification Low Current Positive Voltage Regulator LM78L09M3 SOT-89 Description The LM78L09M3 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 LM78L09M3 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 • No External Components Required Absolute Maximum Ratings (Ta=25 °C) • Input Voltage ....................................................................................................................... 30 V • Total Power Dissipation .................................................................................... Internally limited • Operating Temperature Range .......................................................................... 0 °C to +125 °C • Maximum Junction Temperature ..................................................................................... 125 °C • Storage Temperature Range .......................................................................... -55 °C to +150 °C • Lead Temperature (Soldering 10S).................................................................................. 260 °C Typical Application Schematic Diagram 1 2 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. 576 3.41K 3.89K 7.8K 2.84K 13K 5pF 2.23K GND 1.5K 1.9K 100 100 5K 5.7K Vout Vin LM78L09 Vout Vin 1 3 C1 C2 |
