The MIC5318-3.0YD5-TR is a low-dropout (LDO) linear voltage regulator that offers a regulated output voltage of 3.0 V with a drop-out voltage of 0.5 V. The regulator is suitable for applications requiring a regulated output voltage up to 3.0 V, such as microprocessors and digital logic circuits. It features very low quiescent current (less than 20 μA typ) and low drop-out voltage (0.5 V typ).

The MIC5318-3.0YD5-TR regulator is designed to operate as either a fixed or adjustable regulator. If used as a fixed voltage regulator, it will provide a regulated output voltage at an accuracy of better than 1.4%. If used as an adjustable regulator, the voltage is programmed using an external resistor divider. The MIC5318-3.0YD5-TR has a shutdown function which can be used to turn off the device. This is useful for applications where the load current needs to be limited, such as when powering a radio.

The MIC5318-3.0YD5-TR LDO regulator is offered in an SO-20 package, which offers a small footprint and low thermal resistance. Other features include high ripple rejection and a current limiter that protects the internal circuit from over-current and short-circuit events.

The MIC5318-3.0YD5-TR uses a voltage reference, current sources and error amplifiers to regulate the output voltage. The regulator works by comparing the output voltage to a reference voltage and then compensating for any error by increasing or decreasing the output current. In doing so, the regulator is able to maintain a constant output voltage. This is known as “Feedback Control” and is the underlying principle of most regulators.

The MIC5318-3.0YD5-TR can be used in a wide range of electronic applications, including computers, consumer electronics, automotive, industrial and medical. It is ideal for supplying low-power circuits such as microprocessors, digital logic and small displays. The low drop-out voltage, high ripple rejection and current limiter make the MIC5318-3.0YD5-TR a great choice for applications that require precise and efficient voltage regulation.
