1 / 13 page TL783 HIGH-VOLTAGE ADJUSTABLE REGULATOR SLVS036E – SEPTEMBER 1981 – REVISED FEBRUARY 2000 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Output Adjustable From 1.25 V to 125 V When Used With an External Resistor Divider D 700-mA Output Current D Full Short-Circuit, Safe-Operating-Area, and Thermal-Shutdown Protection D 0.001%/V Typical Input Voltage Regulation D 0.15% Typical Output Voltage Regulation D 76-dB Typical Ripple Rejection D Standard TO-220AB Package description The TL783 is an adjustable three-terminal high-voltage regulator with an output range of 1.25 V to 125 V and a DMOS output transistor capable of sourcing more than 700 mA. It is designed for use in high-voltage applications where standard bipolar regulators cannot be used. Excellent performance specifications, superior to those of most bipolar regulators, are achieved through circuit design and advanced layout techniques. As a state-of-the-art regulator, the TL783 combines standard bipolar circuitry with high-voltage double-diffused MOS transistors on one chip to yield a device capable of withstanding voltages far higher than standard bipolar integrated circuits. Because of its lack of secondary-breakdown and thermal-runaway characteristics usually associated with bipolar outputs, the TL783 maintains full overload protection while operating at up to 125 V from input to output. Other features of the device include current limiting, safe-operating-area (SOA) protection, and thermal shutdown. Even if ADJ is inadvertently disconnected, the protection circuitry remains functional. Only two external resistors are required to program the output voltage. An input bypass capacitor is necessary only when the regulator is situated far from the input filter. An output capacitor, although not required, improves transient response and protection from instantaneous output short circuits. Excellent ripple rejection can be achieved without a bypass capacitor at the adjustment terminal. The TL783C is characterized for operation over the virtual junction temperature range of 0 °C to 125°C.
