GENERAL DESCRIPTION
The PT5107 is a low-dropout voltage regulator
designed for portable and wireless applications
that require high PSRR, low quiescent current
and excellent line and load transient response.
The PT5107 is designed to work with small 1µF
input and output ceramic capacitors. The
quiescent current is as low as 28uA.
With its better than 63dB PSRR at 10kHz, the
PT5107 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 200mA, from a 2.5V to 5.5V input.
The PT5107 consumes less than 0.1µA in
shutdown mode. The PT5107 is available in 5
pin SOT23packages. The output standards of
1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V are available.
