V O Output Voltage. They are intended to control currents of 0. Recommended minimum load capacitance of 0. LM operate from a low-current 5V bias and can convert. If internal power dissipation becomes too. Electrical specifications do not apply when operating the device. These regulators can provide local on card regulation, eliminating the distribution problems associated with ,m78l point regula- tion.

Features n Input power from 2. 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 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 lm78k systems, instrumentation, HiFi, and other solid state electronic equipment. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown cir- cuit takes over preventing the IC from overheating.

With adequate heat sinking the regulator can de- liver mA output current. Physical Dimensions inches millimeters unless otherwise noted Continued.

Minimum Value of Input Voltage. Power up datashheet down sequencing is achieved with the power-good flag, adjustable soft-start and output enable features.

Current limiting is included to. Current limit is achieved by monitoring the voltage drop across the on- resistance of the low-side MOSFET, which enhances low duty-cycle operation. They datashwet intended to control. The adap- tive, non-overlapping MOSFET gate-drivers and high-side bootstrap structure helps to further maximize efficiency.

The LM and LM are high-speed, synchronous.
