DESCRIPTION
The AIC1594 series are step-down monolithic PWM regulators delivering 1A at fixed voltages of 2.5V , 3.3V, 5.0V , 12V and using a external divider to adjust output voltage from 1.25V to 30V with excellent line and load regulation.
Switching frequency up to 150KHz/300KHz are achievable thus allowing smaller sized filter components. Internal current limit and thermal shutdown circuits provide protection from overloads. It also provides output overvoltage and short protection under fault conditions.
The internal precious reference combined with voltage feedback loop provides optimum output voltage accuracy and fast load transient response. Packages available are in standard SOT89-5 and DIP8 for standard assembly and TO263-5, SOP8 for SMD.
