The Texas Instruments LP2985AIM5-3.3/NOPB is a low dropout voltage linear regulator that has the ability to provide output voltages as low as 0.1V. The device is a low power, low dropout (LDO) linear voltage regulator that is designed to run off of a single 3.3V source or battery. The device is available in a thermally enhanced ThinSOT package, making it ideal for use in small, low-power applications where board space is at a premium. The device features wide input voltage range, excellent line and load regulation, adjustable output voltage and overcurrent protection.

The LP2985AIM5-3.3/NOPB operates by way of a very simple principle. The device is a three-terminal device, with an output, an input, and a ground. The output voltage is controlled by a series connected R-L network, within the package. The R-L network is fed by a current from the input, and is regulated by a series connected series pass MOSFET. This MOSFET acts as a variable series resistance between the input and output, depending on the voltage at its gate. The voltage at the gate is regulated by an internal error amplifier, which compares the actual output voltage with a reference voltage. If the actual output voltage is higher, the MOSFET is made to increase its resistance, reducing the current from the input and lowering the output voltage. Similarly, if the output voltage is lower, the error amplifier decreases the gate voltage, causing the MOSFET to reduce its resistance and allowing more current to flow to the output. This process keeps the output voltage regulated to a fixed level.

The LP2985AIM5-3.3/NOPB is ideally suited for battery operated and portable applications, such as telephone systems, handheld devices, notebook computers and similar applications. With its low quiescent current, adjustable output voltage and ability to operate at low voltages, it can be used in a variety of battery-operated and portable applications. Its wide input voltage range, low dropout voltage and low noise make it an ideal power source for modern electronics. Furthermore, its thermally enhanced packaging makes it uniquely suited for use in small, low-power applications where board space is at a premium.
