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 LM1501A LM1501A series operates at a switching frequency of 150kHz. Available in standard 5-lead TO-263, TO-220, TO-220V package. 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 with 5 hysteresis.
