PT5109

PT5109 High-PSRR 300mA LDO GENERAL DESCRIPTION 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. The device can be used for mobile phones and similar battery powered wireless applications. It provides up to 300mA, from a 2.5V to 8V input. The PT5109 consumes less than 0.1µA in shutdown mode. The PT5109 is available in a 5 SOT-23 packages. Selected performances are specified for −40°C to +85°C temperature range. The output voltage is available in the range of 1.8V, 2.5V, 2.8V, 3.0V, 3.3V.
