DESCRIPTION |
| |
The LM1501B series of regulators are monolithic integrated circuits that provide all the active functions for a
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 and TO-220 packages. |

|
|
| Other features include a guaranteed 3% tolerance on output voltage under specified input voltage and output
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'C
with 5'C hysteresis. |
