LT3063EMS8E#PBF - Low Dropout Linear Regulator

The LT3063EMS8E#PBF from Linear Technology is a high-performance, low dropout (LDO) linear regulator that offers excellent stability and power supply rejection ratio (PSRR) characteristics. This device is designed to provide precision voltage regulation with an adjustable output from 1.21V to 20V, which makes it a versatile choice for a wide range of applications.

Encased in an MSOP-8 package, the LT3063 is capable of delivering up to 100mA of continuous output current with a low dropout voltage of only 300mV at full load. This feature allows for efficient operation even when the input-to-output voltage differential is minimal, making it ideal for battery-powered devices where maximizing battery life is crucial.

The LT3063EMS8E#PBF incorporates several protective features that ensure the safety and reliability of both the regulator and the system it powers. These include over-current protection, reverse battery protection, and thermal shutdown. Additionally, the device has a low quiescent current of 30μA (typical) in operation and less than 3μA in shutdown, further enhancing its suitability for portable and battery-operated equipment.

One of the key benefits of this LDO is its low noise performance, with only 30μV RMS of output noise over a 10Hz to 100kHz bandwidth when using a 10μF bypass capacitor. This makes the LT3063EMS8E#PBF an excellent choice for sensitive RF and audio applications that require a clean and stable power supply.

Another feature of the LT3063 is its ability to operate with a very small ceramic output capacitor, which can be as small as 2.2μF, thus reducing the overall footprint and cost of the power supply design. The device also features an internal charge pump that allows the LT3063 to provide a regulated output voltage even when the input voltage falls below the output voltage, further enhancing its flexibility.

In summary, the LT3063EMS8E#PBF from Linear Technology is a highly reliable and efficient LDO regulator that combines low dropout performance, excellent power supply rejection, low noise, and a comprehensive set of protection features. Its wide output voltage range and small package size make it an ideal choice for a broad array of applications, including portable devices, industrial controls, and precision instrumentation.
