PT5128 Dual, High PSRR, 200mA Low Dropout Regulator GENERAL DESCRIPTION The PT5128 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 PT5128 is stable with a small 1µF ceramic capacitor on the output. With its better than 75dB PSRR at 1kHz, the PT5128 is ideal for battery powered systems to deliver low dropout voltage and low quiescent current. This device can be used for mobile phone and similar battery powered wireless applications. It provides up to 200mA at each channel, from a 2.5V to 5.5V input. The PT5128 consumes less than 0.1µA in shutdown mode. The PT5128 is available in 6 pin SOT23 package. The output voltage is available at 1.5V, 1.
