SLVS029B - JANUARY 1984 - REVISED AUGUST 1995
The TL499AC is a monolithic integrated circuit designed to provide a wide range of adjustable regulated supply voltages. The regulated output voltage is adjustable from 2.9 V to 30 V by adjusting two external resistors. When the TL499AC is ac-coupled to line power through a step-down transformer, it operates as a series dc voltage regulator to maintain the regulated output voltage. With the addition of a battery from 1.1 V to 10 V, an inductor, a filter capacitor, and two resistors, the TL499AC operates as a step-up switching regulator during an ac-line failure.
The adjustable regulated output voltage makes the TL499AC useful for a wide range of applications. Providing backup power during an ac-line failure makes the TL499AC extremely useful in microprocessor memory applications.
The TL499AC is designed for operation from -20°C to 85°C.
