The LM and LM are high-speed, synchronous. Power up and down. The high-side power FET drain voltage can be from 2.

Typical thermal resistance values for the packages are: They are intended to control currents of 0. Current limit is achieved by monitoring the voltage drop across the on- resistance of the low-side MOSFET, which enhances low duty-cycle operation. Safe area pro- tection for the output transistors is provided to limit internal power dissipation. Electrical specifications do not apply when operating the device outside of its stated operating conditions.

Power Good flag, adjustable soft-start and output enable. Output over-voltage and under-voltage flag LM 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.


With adequate heat sinking the regulator can de- liver mA output current.

Both parts utilize a fixed. The wide range of operating frequen- cies gives the power supply designer the flexibility to fine- tune component size, cost, noise and efficiency.

The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. LM operate from a low-current datsheet bias and can convert.
