SLVS004G − APRIL 1979 − REVISED SEPTEMBER 2009 D Output Voltage Range Adjustable From D D D D 1.2 V to 32 V When Used With an External Resistor Divider Output Current Capability of 100 mA Input Regulation Typically 0.01% Per Input-Voltage Change Output Regulation Typically 0.5% Ripple Rejection Typically 80 dB D OR PW PACKAGE (TOP VIEW) INPUT OUTPUT OUTPUT ADJUSTMENT 1 8 2 7 3 6 4 5 NC OUTPUT OUTPUT NC NC − No internal connection OUTPUT terminals are all internally connected. description/ordering information PS PACKAGE (TOP VIEW) The TL317 is an adjustable three-terminal positive-voltage regulator capable of supplying 100 mA over an output-voltage range of 1.2 V to 32 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. In addition to higher performance than fixed regulators, this regulator offers full overload protection available only in integrated circuits. Included on the chip are current-limiting and thermal-overload protection. All overload-protection circuitry remains fully functional, even when ADJUSTMENT is disconnected. Normally, no capacitors are needed unless the device is situated far from the input filter capacitors, in which case an input bypass is needed. An optional output capacitor can be added to improve transient response. ADJUSTMENT can be bypassed to achieve very high ripple rejection, which is difficult to achieve with standard three-terminal regulators. INPUT NC NC NC 1 8 2 7 3 6 4 5 OUTPUT NC ADJUSTMENT NC NC − No internal connection LP PACKAGE (TOP VIEW) INPUT OUTPUT ADJUSTMENT In addition to replacing fixed regulators, the TL317 regulator is useful in a wide variety of other applications. Since the regulator is floating and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input-to-output differential is not exceeded. Its primary application is that of a programmable output regulator, but by connecting a fixed resistor between ADJUSTMENT and OUTPUT, this device can be used as a precision current regulator. Supplies with electronic shutdown can be achieved by clamping ADJUSTMENT to ground, programming the output to 1.2 V, where most loads draw little current. The TL317C is characterized for operation over the virtual-junction temperature range of 0°C to 125°C. The TL317 is characterized for operation over the virtual-junction temperature range of −20°C to 125°C.
