BL9169

300mA,Ultra-low noise, Small Package

Ultra-Fast CMOS LDO Regulator

General Description

The BL9169 is designed for portable RF and wireless applications with demanding performance and

space requirements. The BL9169 performance is optimized for battery-powered systems to deliver

ultra low noise and low quiescent current. The BL9169 also works with low-ESR ceramic capacitors,

reducing the amount of board space necessary for power applications, critical in hand-held wireless

devices.

The BL9169 has fast turn-on time less than 50µs. The other features include ultra low dropout

voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. It is

available in the 5-lead of SOT23-5 and TSOT23-5 packages.
