LM317LILP

The LM317LILP is an adjustable 3-terminal Positive-Voltage Regulator capable of supplying 100mA over an output-voltage range of 1.25 to 32V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. The device has a feedback voltage that is relative to the output instead of ground. This ungrounded design allows the device to have superior line and load regulation. This design also allows the device to be used as a current source or current sink using a single resistor. In addition to higher performance than fixed regulators, this regulator offers full overload protection, available only in integrated circuits. Included on the chip is 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.

• Input regulation typically 0.01% per input-voltage change
• 0.5% Typically output regulation
• 80dB Typically ripple rejection
