LDLN015PU18R is a member of the Linear Voltage Regulators product family. This specific model belongs to a wide variety of linear voltage regulator applications and has a variety of useful features that make it well-suited for powering a wide range of electrical and electronic devices. These features include high power efficiency and accuracy, low dropout voltage, low temperature drift, and low power consumption.

The LDLN015PU18R is a linear low dropout voltage regulator designed to provide a regulated output voltage from a limited input voltage. This device operates from an input voltage range of 3.0V to 20V. The output voltage is adjustable from 1.25V to 18V with an accuracy of 5%. The output current is limited to 0.15A maximum and is biased by a trimming potentiometer. The device includes a temperature-compensated top-stage voltage reference and three-terminal current-limiting circuitry.

The LDLN015PU18R is particularly suitable for a wide range of portable electronic applications such as cell phones, PDAs, and digital cameras because of its low power consumption, high power efficiency, and low-dropout voltage regulation capability. Its low voltage operation allows the device to be powered from either a 3.0V lithium battery or a wall adapter. Its low power consumption and its own built-in power regulator make it well-suited for battery-powered system applications.

The LDLN015PU18R supports both buck and boost operation for improved power efficiency, and its accuracy is improved by its adjustable voltage reference. Its wide temperature range makes it suitable for use in both industrial and commercial applications. This device also works with high ripple noise, allowing for use in a variety of challenging environments.

Furthermore, the LDLN015PU18R has a programmable over-temperature shutoff circuit and a low dropout voltage (less than 0.63V), in order to maintain the highest efficiency over its entire operating range of input voltage. The device also has a linear current limit, which keeps the output current at a safe level even under worst case operating conditions. This feature is particularly useful in battery-powered systems, where an overcurrent condition could deplete the battery more quickly than expected.
