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.
