Low Current Positive Voltage Regulator SOT-89 LM78L05XM3 Description O G I The LM78L05XM3 series of surface mount regulators are easy-touse 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 LM78L05XM3 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 • Pb-free package 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 Schematic Diagram Typical Application Vin LM78L05 3 Vout Vin 1 5K 5.7K 100 2 100 C1 C2 Note : C1 and C2 are required if regulator is located far from power supply filter and load, or oscillation may induced on the loop. LM78L05XM3 1.9K Vout 5pF 3.41K 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. 1.5K 576 13K 3.89K 2.23K 7.8K 2.84K GND CYStek Product Specification CYStech Electronics Corp.
