AMC DOC. #: AMC79L05_D (LF) March 2004 ADD MICROTECH CORP. AMC79L05 100mA / 3-TERMINAL NEGATIVE VOLTAGE REGULATOR DESCRIPTION FEATURES The AMC79L05 is a 3-terminal fixed negative-voltage designed for a wide range of applications. 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. APPLICATIONS ±5% tolerance of output voltage Wide input range Internal thermal overload protection Output current > 100mA No External Components Short circuit protection Available in 3L plastic TO-92 and plastic 8 pin S.O.I.C. Identical pin assignment to earlier 79L05 series.

All voltages are with respect to Ground. Currents are positive into, negative out of the specified terminal. THERMAL DATA LP PACKAGE: Thermal Resistance-Junction to Ambient, θJA DM PACKAGE: Thermal Resistance-Junction to Ambient, θJA Junction Temperature Calculation: TJ = TA + (PD × θJA). The θJA numbers are guidelines for the thermal performance of the device/pc-board system. All of the above assume no ambient airflow.
