They are intended to control. For applications where latch-off is not de- sired, the LM can be used.
Average Output Voltage Llm78l. 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.
Physical Dimensions inches millimeters unless otherwise noted Continued. The LM employs output over-voltage and under. Output over-voltage and under-voltage flag LM Molded Offset TO Z. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown cir- cuit takes over preventing the IC from pm78l.
Home – IC Supply – Link.
Recommended minimum load capacitance of 0. Safe area pro- tection for the output transistors is provided to limit internal power dissipation.
The high-side power FET drain voltage can be from 2. Current limiting is included to limit the peak output current to a safe value. The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment.
Current limiting is included to. The wide range of operating frequen.

Power up and down. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regula- datwsheet. When used as a zener. Electrical specifications do not apply when operating the device.
The wide range of operating frequen- cies gives the power supply designer the flexibility to fine- tune component size, cost, datxsheet and efficiency.
Power up and down sequencing is achieved with the power-good flag, adjustable soft-start and output enable features. With adequate heat sinking the regulator can de.
Human body model, 1. The LM employs output over-voltage and under- voltage latch-off. Features n Input power from 2.
Electrical specifications do not apply when operating the device outside of its stated operating conditions. Required to Maintain Line Regulation.
Current limit is achieved by monitoring the voltage drop across the on- resistance of the low-side MOSFET, which enhances low duty-cycle operation. Output over-voltage satasheet under-voltage latch-off. V O Output Voltage. Power Good flag, adjustable soft-start and output enable.
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. The LM and LM are high-speed, synchronous.
