ON Semiconductor LP2951ACNG Voltage Regulator

The LP2951ACNG is a versatile, micro-power voltage regulator integrated circuit (IC) from ON Semiconductor, designed to offer a variety of features that make it ideal for battery-powered applications. This adjustable and fixed voltage regulator is particularly well-suited for applications requiring a low dropout voltage and low quiescent current.

This device is capable of delivering up to 100 mA of output current while maintaining a low dropout voltage of just 380 mV at a 100 mA load. This characteristic is essential for battery-operated devices, as it helps to maximize the usage of the available battery voltage. Furthermore, the LP2951ACNG includes a host of features such as error flag output, which warns of a low output voltage, often due to falling batteries on the input. Another notable feature is the logic-controlled electronic shutdown, which allows the regulator to be switched off, thus conserving power when not in use.

The LP2951ACNG also offers the convenience of an adjustable output voltage feature, which can be set from 1.23V to 29V with the use of two external resistors. This makes the device highly flexible and adaptable to a wide range of applications. Additionally, the fixed versions are available at 5V, 3.3V, and 3V, which are common voltage levels for digital circuits, making this regulator a go-to choice for standard power supply designs.

Packaged in a standard 8-pin DIP (Dual In-line Package), the LP2951ACNG is easy to integrate into a variety of circuit boards. ON Semiconductor ensures that this product meets the highest quality and performance standards, providing a reliable solution for designers looking to incorporate a stable power supply into their electronic projects.

In summary, the LP2951ACNG from ON Semiconductor is a highly reliable and efficient voltage regulator that offers flexibility, low power consumption, and a suite of protective features, making it an excellent choice for portable devices, instrumentation, and microprocessor or microcontroller power management.
