LT1965EQ-1.8#PBF

The LT1965EQ-1.8#PBF voltage regulator is a linear voltage regulator that belongs to the PMIC (Power Management Integrated Circuit) family. It is used to control the output voltage of a circuit, making it possible to a wide range of output voltage levels. The device will maintain the output voltage at the set level even when the external load current varies. It is designed to be highly efficient and stable in its operation while providing optimal protection against voltage and current spikes.

The primary application field of the LT1965EQ-1.8#PBF is for power management of mobile and consumer electronics, such as laptops, tablets, cell phones, smart phones and other portable devices. It is also suitable for applications such as battery-powered equipment and LED lighting. The output voltage is adjustable and can be set up to 1.8V.

The LT1965EQ-1.8#PBF is available in an SOT-23 package and comes with an on-board precision voltage reference, voltage error amplifier and current-limit circuitry. It is able to provide fast transient responses and a 100mA output current with a low dropout voltage of 0.5V (under specified conditions). It has a wide input voltage range from 2.2V to 6V and a high shutdown current of 0.9μA.

The LT1965EQ-1.8#PBF is a single-channel device and the output voltage is regulated by means of an internal symmetrical current source compared to a voltage reference. The device senses the voltage across a resistor connected to the output, and adjusts the current source accordingly to maintain the output voltage constant. This method gives excellent regulation with minimal ripple and minimal variation in the output voltage over a wide range of line and load conditions.

The LT1965EQ-1.8#PBF has various protection features, including thermal shutdown and current limit. The device has a separate enable pin that allows the user to turn off the device when required, and a low dropout feature that allows it to be used in Emergency Shutdown applications. The device also has an on-chip current-limit feature that limits the output current when it exceeds a programmed threshold.

The LT1965EQ-1.8#PBF is an ideal choice for cost-sensitive high-efficiency voltage regulation applications. It is a low-power and low-noise device that is able to provide high accuracy and excellent linear regulation. It also has a wide input voltage range and is able to provide fast transient response. With its protection features and adjustable output, the LT1965EQ-1.8#PBF is a highly versatile device suitable for a wide range of applications.
