150mA dual LDO for battery-powered designs

May 06, 2015 // By Graham Prophet
Offering low noise and small size for battery-powered portable equipment, the AP7342 low dropout regulator (LDO) has dual 150mA outputs with high 1% voltage accuracy from a 1.7V to 5.25V input voltage range.

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

The AP7342 has 75dB power supply rejection ratio (PSRR) and 60 μVrms noise sensitivity (from 10 Hz to 100 kHz). 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 +25C and 1.5% across the full -40C to +85C operating temperature range.

AP7342 is priced at $0.25 (5000).
