This document provides all the necessary specifications, characteristics, and application information needed to effectively utilize this component in your designs. Grasping the details within the LP2985 33DBVR Datasheet is essential for engineers and hobbyists aiming to optimize power consumption and ensure stable voltage regulation.
Understanding the LP2985 33DBVR Datasheet and Its Applications
The LP2985 33DBVR Datasheet describes a low-dropout (LDO) voltage regulator specifically designed for efficiency. LDOs are a type of linear regulator that can maintain a stable output voltage even when the input voltage is only slightly higher than the desired output. The “33” in “LP2985 33DBVR” indicates that this particular variant provides a fixed output voltage of 3.3V. This makes it ideal for powering microcontrollers, sensors, and other digital circuits that require a stable 3.3V supply. Its low dropout voltage is critically important as it allows the regulator to continue functioning correctly even as the battery voltage decreases.
The datasheet contains a wealth of information, including:
- Absolute maximum ratings (voltages, currents, temperatures)
- Electrical characteristics (input voltage range, output voltage accuracy, quiescent current)
- Typical performance characteristics (load regulation, line regulation, transient response)
- Application information (recommended external components, thermal considerations)
These details enable a designer to properly assess the suitability of the LP2985 33DBVR for a given application, select appropriate external components, and ensure reliable operation over a range of conditions.
Applications for the LP2985 33DBVR are diverse, including:
- Battery-powered devices (smartphones, tablets, wearables)
