PT5127
Dual Outputs 200mA High PSRR LDO
GENERAL DESCRIPTION
The PT5127 is a dual channel 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 PT5127 is stable with a small 1µF ceramic capacitor on the output. With its better than 75dB PSRR at 1kHz, the PT5127 is ideal for battery powered systems for delivering low dropout voltage and low quiescent current. This device can be used for mobile phones and similar battery powered wireless applications. It provides up to 200mA at each channel, from a 2.0V to 5.5V input. The PT5127 consumes less than 0.1µA in shutdown mode. The PT5127 is available in 6 pin SOT23 package. The output voltage is available at 1.8V, 2.5V, 2.8V, 3.
