RT9187PQV Description

Short technical summary and product information.

The RT9187PQV from Richtek is a high-performance, 1A LDO regulator characterized by its extremely high PSRR and ultra-low dropout voltage. This makes it an ideal choice for portable RF and wireless applications where performance and space are critical.

 

Key features include an ultra-low dropout voltage of 240mV at 1A, a wide operating voltage range from 2.5V to 5.5V, and a fast turn-on time of less than 40μs. The regulator also offers a standby current of less than 0.1μA in shutdown mode, contributing to extended battery life. A noise reduction pin is available for further reduction of output noise.

 

The RT9187PQV is designed to work with low-ESR ceramic capacitors, reducing board space requirements, which is crucial for hand-held wireless devices. It also includes essential protection features such as current limiting and thermal shutdown protection. The regulator is available in VDFN-8L 3x3 and SOP-8 (Exposed Pad) packages, supporting surface mount applications.

 

This LDO regulator is suitable for applications such as CDMA/GSM cellular handsets, battery-powered equipment, laptop computers, hand-held instruments, and various portable information appliances.
