LM2937ES-10

The LM2937ES-10 is a low quiescent (passive) current linear voltage regulator designed for a wide range of applications, from personal digital assistant (PDA) systems to automotive, industrial and other markets. It is a regulator designed to provide fixed and adjustable output voltages from 2.5V to 6V, providing power for standard linear voltage regulators, current sources and low noise power supplies. It is designed to be used in battery powered systems, providing a simple and economical means of regulating and controlling current output from the battery.

The LM2937ES-10 offers high-performance features such as low output noise, low shutdown current and high input-to-output voltage ratio. It operates with a low-dropout voltage of typically 0.5 volts and offers a wide input voltage range (from typically 2.5V to 6V). The regulator is also capable of delivering up to 600 mA output current.

The LM2937ES-10 works on the principle that the voltage across a constant-current regulator follows the input voltage. In this type of regulator, a field effect transistor (FET) is used as the active element to adjust the output current. The current supplied to the load is controlled by the voltage across the FET. The FET is controlled using a feedback loop, which senses the output voltage, compares it to a reference voltage, and then adjusts the current via the FET to ensure the output voltage stays constant.

The LM2937ES-10 can be used to provide adjustable output up to 6V with a maximum current of 600 mA. The adjustable output is especially useful for situations where the load can vary from one application to another. For example, if a 5V regulator is required for an application that uses a 4V load, the current output from the LM2937ES-10 can be adjusted to accommodate the smaller load. This makes it an ideal solution for applications that require a voltage regulator with an adjustable output.

The LM2937ES-10 is perfect for applications with tight space constraints due to its small size. The package is lead-free and RoHS compliant. The device is also designed to withstand high temperature operation (up to 125°C) and is qualified for automotive applications.

The LM2937ES-10 provides easy-to-use, high efficiency, and cost-effective solutions for a variety of power requirements. It can be used in numerous applications including automotive, industrial, telecommunications, lighting, and consumer electronics. With its high-performance features, low power consumption, and a wide input-to-output voltage ratio, the LM2937ES-10 is the perfect choice for easily powering any system from 2.5V to 6V.
