LP3992-28B5F Description

Short technical summary and product information.

The LP3992-28B5F from LOWPOWER is a 2.8V, 300mA CMOS Low Dropout (LDO) regulator optimized for portable RF and wireless applications. It is designed for battery-powered systems, delivering ultra-low noise and low quiescent current.

 

Key electrical features include an ultra-low dropout voltage, high output accuracy, current limiting protection, and a high ripple rejection ratio. The regulator consumes less than 0.01μA in shutdown mode and boasts a fast turn-on time of less than 50μs. It is compatible with low-ESR ceramic capacitors, which helps reduce board space requirements.

 

This LDO regulator is suitable for applications such as Portable Media Players/MP3 players, Cellular and Smart mobile phones, LCD displays, DSC sensors, and Wireless Cards. It is available in the 5-lead SOT23-5 and TSOT23-5 packages, making it ideal for space-constrained designs.
