Diodes Incorporated's new AP7346 dual low-dropout (LDO) voltage regulator is designed to provide power and I / O power to fingerprint recognition modules used in smartphones, tablets and similar consumer electronics.
The device's low quiescent current and high efficiency at light loads can minimize the power consumption of such portable battery-powered devices, while the 1.2mm x 1.2mm miniature package (only 0.4mm in height) saves space .
The wide input voltage range of 1.7V to 5.25V allows the regulator to work during the entire Li-ion battery charge / discharge cycle and provides an output voltage of 1.2V to 3.6V in fixed 0.1V steps, accurate to the entire temperature range The 1.5% range is -40C to + 85C. AP7346 also has a high precision current limit of 157mA ± 25mA and a low quiescent current of 35μA, which helps to extend standby and use time. In addition, the enable input allows the output to be turned off as needed.
The regulator is housed in an X2-DFN1212-6 package and has a high power supply ripple rejection ratio of 75dB and low noise performance of 60μVRMS, making it particularly attractive in noise, audio, video and RF communications applications.
