5.0A, 300kHz, Step-down Switching Regulator

Absolute Maximum Ratings

Note 1. Absolute Maximum Rating indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test

conditions, see the Electrical Characteristics.

FEATURES

APPLICATION

DESCRIPSION

step-down switching regulator, capable of driving a 5A load with excellent line and load regulation. These

devices are available in fixed output voltages of 3.3V, 5V, 12V and an adjustable output version. Requiring a

minimum number of external components, these regulators are simple to use. The LM1501B series operates at

a switching frequency of 300kHz. Available in standard 5-lead TO-263, TO-220, TO-220V packages.

load conditions, and ± 15% on the oscillator frequency. External shutdown is included, featuring typically 80uA

standby current. Self protection features include a current limit for output switch and an over temperature

shutdown for complete protection under fault conditions. The over temperature shutdown level is about 145℃

with 5℃ hysteresis.
