The AP7342 low dropout regulator (LDO) introduced by Diodes Incorporateddelivers dual 150mA outputs with high 1% voltage accuracy from a wide 1.7V to 5.25V input voltage range. With a low 35µA quiescent current, low RDS(ON) and tiny 6-pin X2 DFN1212 package, this part is particularly well-suited for compact, low-power, handheld, consumer electronic products such as smart phones, tablets, cameras and portable media players.
Additional benefits of the AP7342 are a high 75dB power supply rejection ratio (PSRR) and low 60μVrms noise sensitivity (from 10Hz to 100kHz). These are key to getting the best performance from audio and video applications or communications devices with RF sub-systems, such as wireless adaptors. A wide input voltage specification ensures compatibility with lithium batteries down to 1.7V, while the output voltage, which can be fixed between 1.2V and 3.6V, is maintained to 1% accuracy at +25 degrees C and 1.5% across the full -40 to +85 degrees C operating temperature.
