LP2953AIN-3.3 is an ultra-low-dropout linear voltage regulator designed to fulfill the needs of portable and mobile system applications. It provides a 3.3V power supply for the system, offering up to 150mA of output current and a low quiescent current of only 24mA. The low-dropout voltage of this regulator is 0.3V, which allows the output to remain stable and reliable even when the input voltage is close to the output voltage. This feature makes LP2953AIN-3.3 an ideal choice for applications in which high efficiency and low power consumption are crucial.

LP2953AIN-3.3 is a three-terminal adjustable device, which features an adjustable pin for setting the output voltage to any voltage between 1.23V to 5.0V with only two external resistors. The output current capability is limited to 150mA, and the output current must never exceed this.The regulator also features a power-good indicator which indicates the output voltage is within tolerance and is ready to use. It also has a wide operating temperature range of -40°C to +85°C and its low quiescent current makes it ideal for battery-powered systems.In addition, the device is short-circuit protected and has thermal overload protection to protect against overheating.

At the heart of this device is an advanced low-power design that integrates the switching MOSFET and the voltage reference into a high-performance monolithic setup. It achieves an ultra-low quiescent current, which results in improved power efficiency and low power consumption. The bias current of the device is only 7uA, and the low voltage drop across the device helps to minimize power dissipation.

In addition, the device also has built-in reverse-voltage protection and over-voltage protection to protect the system from any voltage spikes that may occur. The LP2953AIN-3.3 operates on a wide input range of 2.7V to 5.5V and is offered in the 8-lead SOIC package. It is RoHS compliant and has the capability to handle up to 2A of surge current.

LP2953AIN-3.3 is an ideal choice for applications such as digital TVs and digital signage, automotive infotainment systems, mobile accessories and devices, audio equipment, tablets, and embedded systems. The device ensures a stable, reliable power supply with maximum efficiency and low power consumption even when the input voltage is close to the output voltage.

Overall, LP2953AIN-3.3 offers a robust and efficient solution for powering systems that require high efficiency and low power consumption. This device provides reliable and stable power, with the protection features to ensure it does not get damaged by voltage spikes that may occur. With its wide input voltage range, low quiescent current, adjustable output voltage and maximum output current of 150mA, LP2953AIN-3.3 is the perfect choice for any system requiring a high-performance and efficient power source.
