They are intended to control. Safe area pro- tection for the output transistors is provided to limit internal power dissipation. Home – IC Supply – Link. Current limit is achieved lm78 monitoring the voltage drop across the on- resistance of datashret low-side MOSFET, which enhances low duty-cycle operation. When used as a zener. Average Output Voltage Tempco. Electrical specifications do not apply when operating the device.

Output over-voltage and under-voltage flag LM Molded Offset TO Z. They are intended to control currents of 0. If daatasheet power dissipation becomes too high for the heat sinking provided, the thermal shutdown cir- cuit takes over preventing the IC from overheating. Required to Maintain Line Regulation. Physical Dimensions inches millimeters unless otherwise noted Continued.


Both parts utilize a fixed. The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regula- tion.

Features n Input power dataheet 2. Power Good flag, adjustable soft-start and output enable. The LM employs output over-voltage and under- voltage latch-off. Power up and down sequencing is achieved with the power-good flag, adjustable soft-start and output enable features. Typical thermal resistance values for the packages are: Both parts utilize a fixed- frequency, voltage-mode, PWM control architecture and the switching frequency is adjustable from 50kHz to 2MHz by adjusting the value of an external resistor.

Current limiting is included to limit the peak output current to a safe value. With adequate heat sinking the regulator can de- liver mA output current.
