TL317 SLVS004H - APRIL 1979 - REVISED OCTOBER 2011 www.ti.com 3-TERMINAL ADJUSTABLE REGULATOR Check for Samples: TL317 FEATURES 1 * * * * * Output Voltage Range Adjustable From 1.25 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 PACKAGE (TOP VIEW) INPUT OUTPUT OUTPUT ADJUSTMENT 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. 8 2 7 3 6 4 5 NC OUTPUT OUTPUT NC NC No internal connection OUTPUT terminals are all internally connected. DESCRIPTION The TL317 is an adjustable three-terminal positive-voltage regulator capable of supplying 100 mA over an output-voltage range of 1.25 V to 32 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. 1 PW PACKAGE (TOP VIEW) INPUT NC NC ADJUSTMENT 1 8 2 7 3 6 4 5 NC NC OUTPUT NC NC No internal connection PS PACKAGE (TOP VIEW) 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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
