LM78L Datasheet

Both parts utilize a fixed- frequency, voltage-mode, PWM control architecture datasheey the switching frequency is adjustable from 50kHz to 2MHz by adjusting the value of an external resistor.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

They are intended to control currents of 0. Physical Dimensions inches millimeters unless otherwise noted Continued.

The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. The wide range of operating frequen- cies gives the power supply designer the flexibility to fine- tune component size, cost, noise and efficiency.

Minimum Value of Input Voltage. Average Output Voltage Tempco. For applications where latch-off is not de- sired, the LM can be used.

Power up and down. Current limit is achieved by monitoring the voltage drop across the on- resistance of the low-side MOSFET, which enhances low duty-cycle operation. Home – IC Supply – Link. Molded Offset TO Z. The LM employs output over-voltage and under- voltage latch-off.
