Low Current Positive Voltage Regulator LM78LXXM3 SOT-89 O G I Description The LM78LXXM3 series of positive regulators are available in the SOT-89 package and with 5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V and 24V fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 100mA output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. LM78LXXM3 is characterized for operation from 0℃ to 125℃. Features: • Internal Short-Circuit Current Limiting • Internal Thermal Overload Protection • No External Components Required • Pb-free package Schematic Diagram Typical Application Vin LM78LXX 3 Vout Vin 1 5K C1 C2 5.7K 100 2 100 1.5K 576 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. Note : C1 and C2 are required if regulator is located far from power supply filter and load, or oscillation may induced on the loop.
