Linear voltage regulators provide a minimum of component regulation of loads. They are very simple, but still adequate for most applications in the market. The NCP4686DSN12T1G is an example of the linear voltage regulators made by ON Semiconductor. This particular device is a Low Dropout (LDO) Linear Voltage Regulator, capable of regulating output voltages between 6V and 16V in a variety of applications. It is available in a 3-pin SOT-223 package.

The NCP4686DSN12T1G is suitable for a wide range of applications, including automotive and industrial systems, point of load regulation, telecommunications, computer systems and battery charging. This LDO regulator is especially tailored for the use with Lead-acid batteries or Nickel Metal Hydride batteries.

This linear regulator can supply up to 1A of load current, making it ideal for moderate load applications. It has an on-chip thermal cutoff built-in, together with other protections to ensure overall system protection. There is an Enable/Disable logic control feature to save power and provide a shutdown mode.

The device has dual high precision references and integrated current-limit circuitry, making it a reliable option to provide accurate voltage regulation. It has a maximum dropout voltage of 1.1V at full load, providing plenty of headroom for applications where the load varies over time or high transient loads.

The NCP4686DSN12T1G has a PWM, pulse-skipping and pulse-frequency modulation control, providing a high power capability to medium power applications. The output voltage is sensed and compared to an internal reference voltage to provide a stable voltage across the output even under varying load conditions.

The linear regulator also features an internal current limit, as well as thermal and overvoltage protection for additional safety. The internal current limit and overvoltage protection features may be disabled via the enable pin, providing improved load and line regulation parameters.

Overall, the NCP4686DSN12T1G is a low dropout linear voltage regulator, offering excellent performance and reliability in various demanding applications. With its wide input voltage range and wide output voltage range, this linear regulator is designed to provide accurate, low-noise regulation even in the most challenging applications. It also offers superb transient response, thermal protection, overvoltage protection and excellent PSRR, packages in an industry standard 3-pin SOT-223 housing.
