AMC78L05
www.addmtek.com DESCRIPTION The AMC78L05 is a 3-terminal positive regulator with a fixed output voltage of 5V. Although it is designed as a fixed-voltage regulator, the output voltage can be increased by the use of a simple voltage divider. This regulator can provide local on card regulation, eliminating the distribution problems associated with single point regulation. In addition, it can be used with power-pass elements to make high-current voltage regulators with 100mA output current. Protection features such as thermal shutdown and current limiting have been designed internally which will protect the device from damage in case of overload or overheating.

1.For PK package, Thermal Resistance-Junction to Tab ( JT ) = 35 OC/W. TJ = TTAB + (PD x JT). PD: Power Dissipation. 2.JA: Thermal Resistance-Junction to Ambient Junction Temperature Calculation: TJ = TA + (Pd x ja). The ja numbers are guidelines for the thermal performance of the device/PC-board system. All of the above assume no ambient airflow.
