Electrical specifications do not apply when operating the device. Electrical specifications do not apply when operating the device outside of its stated operating conditions. Output over-voltage and under-voltage flag LM Both parts utilize a fixed. The high-side power FET drain voltage can be from 2.

With adequate heat sinking the regulator can de. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regula- tion. The wide range of operating frequen. With adequate heat sinking the regulator can de- liver mA output current.

Power up and down.

Minimum Value of Input Voltage. Current limit is achieved by monitoring the voltage drop across the on- resistance of the low-side MOSFET, which enhances low duty-cycle operation. If internal power dissipation becomes too. The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. Power up and down sequencing is achieved with the power-good flag, adjustable soft-start datashheet output enable features.

Typical thermal resistance values for the packages are: The LM and LM are high-speed, synchronous. V O Output Voltage. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown cir- datashret takes over preventing the IC dtasheet overheating.


Average Output Voltage Tempco. Human body model, 1. Safe area pro- tection for the output transistors is provided to limit internal power dissipation. LM operate from a low-current 5V bias and can convert. The LM employs output over-voltage and under- voltage latch-off. For applications where latch-off is not de.

Features n Input power from 2. Current limiting is included to limit the peak output current to a safe value.

Molded Offset TO Z. 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. The adap- tive, non-overlapping MOSFET gate-drivers and high-side bootstrap structure helps to further maximize efficiency. For applications where latch-off is not de- sired, the LM can be used. Power Good flag, adjustable soft-start and output enable.
