description
The TL499A is an integrated circuit designed to provide a wide range of adjustable regulated supply voltages.
The regulated output voltage can be varied from 2.9 V to 30 V by adjusting two external resistors. When the
TL499A 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 TL499A operates as a step-up switching regulator during an ac-line failure.
The adjustable regulated output voltage makes the TL499A useful for a wide range of applications. Providing
backup power during an ac-line failure makes the TL499A extremely useful in microprocessor memory
applications.
The TL499AC is characterized for operation from –20
°C to 85°C.
