GENERAL DESCRIPTION
FEATURES
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 TD1509 is available in SOP8 and DIP8 packages. z 5V,3.3V and adjustable output versions z Output adjustable from 1.23v to 43V z Fixed 150KHz frequency internal oscillator z Guaranteed 3A output load current z Input voltage range up to 45V z Low power standby mode, IQ typically 80 µA z TTL shutdown capability z Excellent line and load regulation z Requires only 4 external components z High...
