PT5109 Datasheet (Powtech) - High-PSRR 300mA LDO

PT5109, High-PSRR 300mA LDO

The PT5109 is a low-dropout voltage regulator designed for portable applications that require both low noise performance and board space.

Its PSRR at 1kHz is better than 60dB.

The PT5109’s is ideal for battery powered systems for delivering low dropout voltage and low quiescent current.
