Small regulator for portable equipment

Diodes Incorporated has introduced the AP7342 low dropout regulator, which delivers dual 150mA outputs with high 1% voltage accuracy from a 1.7 to 5.25V input voltage range.

With a 35µA quiescent current, low RDS(ON) and a 6-pin X2-DFN1212 package, this regulator is suited for compact, low-power, handheld, consumer electronic products such as smart phones, tablets, cameras and portable media players.

Additionally the AP7342 has a 75dB power supply rejection ratio and 60µVrms noise sensitivity (from 10Hz to 100kHz). These are significant to getting performance from audio and video applications or communications devices with RF sub-systems, such as wireless adaptors.

Its 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 1.5% across the full -40 to 85oC operating temperature.
