LM78L12Q8

CYStech Electronics Corp. Low Current Positive Voltage Regulator LM78LXXQ8 Spec. No. : C515Q8 Issued Date : 2007.11.19 Revised Date : 2013.07.08 Page No. : 1/11 SOP-8 Description The LM78LXXQ8 series of positive regulators are available in the SOP-8 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. LM78LXXQ8 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 Typical Application Schematic Diagram Vin 3 C1 LM78LXX 2 Vout 1 C2 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....
