These devices are available in fixed output voltage of 3.3V, 5V, and an adjustable output version. Both versions are capable of driving a 3A load with excellent line and load regulation. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator. The output voltage is guaranteed to ±3% tolerance under specified input voltage and output load conditions. The oscillator frequency is guaranteed to ±15%. External shutdown is included, featuring typically 80 µA standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions. The TD1501 is available in TO-220B-5L TO220-5L and TO-263-5L packages.   3.3V, 5V and adjustable output versions Output adjustable from 1.23v to 43V Fixed 150KHz frequency internal oscillator Guaranteed 3A output load current Input voltage range up to 45V Low power standby mode, IQ typically 80 µA TTL shutdown capability Excellent line and load regulation Requires only 4 external components High efficiency Thermal shutdown and current limit protection Available in TO-220B...
