lm778l The LM employs output over-voltage and under. They are intended to control currents of 0. Electrical specifications do not apply when operating the device outside of its stated operating conditions.

The high-side power FET drain voltage can be from 2. Features n Input power from 2. Power up and down. Power Good flag, adjustable soft-start and output enable.

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. Both parts utilize a fixed. Safe area pro- tection for the output transistors is provided to limit internal power dissipation. For applications where latch-off is not de.

If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown cir- cuit takes over preventing the IC from overheating. Average Output Voltage Tempco.

For applications where latch-off is not de- sired, the LM can be used.

The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. Minimum Value of Input Voltage. Electrical specifications do not apply when operating the device. Current limiting is included to limit the peak output current to a safe value.


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- liver mA output current. Output over-voltage and under-voltage flag LM Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

When used as a zener. V O Output Voltage.

The wide range of operating frequen- cies gives the power supply designer the datasueet to fine- tune component size, cost, noise and efficiency. With adequate heat sinking the regulator can de. Typical thermal resistance values for the packages are: Output over-voltage and under-voltage latch-off. The adap- tive, non-overlapping MOSFET gate-drivers and high-side bootstrap structure helps to further maximize efficiency.

The LM employs output over-voltage and under- voltage latch-off. Current limiting is included to.
