The LM317LCLPRE3 is a programmable precision voltage regulator IC primarily used in a number of systems and power supply applications. It is a low-dropout (LDO) regulator and is typically used for post regulation of the discharged output voltage from a DC/DC converter. Designed for a wide input voltage range, the LM317LCLPRE3 is suitable for many different types of linear power supplies.

The LM317LCLPRE3 is a three-terminal adjustable regulator. It is capable of output voltages from 1.5 up to 31 volts, with a precision of 0.5% guaranteed over the output voltage of 1.5 V to 6 V. It is a low dropout regulator whose output can be adjusted down to 1.25V. The maximum input voltage is 40V, and it can supply up to 3A of current. Its output accuracy is better than 1% over temperature and its operating temperature range is -40 to +125°C. It is suitable for both high and low voltage circuits, either to regulate the voltage as desired, or to protect the output from overvoltage and shorting.

The LM317LCLPRE3 is designed to minimize the effects of power supply transients and other noise sources to keep the voltage output stable and within tolerance. Its error-amplifier output is pinned out separately from the adjustable pin, which allows the user to take the output voltage swing without the load effect on the regulator. It also has a built-in voltage reference for the adjustable voltage, providing a very stable regulation of the output voltage within the required range.

The LM317LCLPRE3 features an over-current protection (OCP) circuit which cuts off the output voltage if the output current increases beyond a predetermined level. This makes the LM317LCLPRE3 ideal for power supply applications where current and voltage are critical. In addition, it has thermal shutdown, which automatically shuts down the output voltage in the event the IC overheats. For improved accuracy and reliability, it also has a low-noise input reference voltage and a wide temperature range.

The LM317LCLPRE3 is a versatile chip that can be used in a wide range of applications. It can be used to create adjustable power supplies, regulator modules, and other voltage-sensitive systems. It can be used to regulate the voltage of an output voltage to a predetermined value, or to protect the output from overvoltage and shorting. In summary, the LM317LCLPRE3 is a highly reliable programmable precision voltage regulator chip suitable for a wide range of applications.
