LDO delivers dual 150mA outputs with 1% voltage accuracy

LDO delivers dual 150mA outputs with 1% voltage accuracy
An LDO that delivers dual 150mA outputs with high 1% voltage accuracy from a wide 1.7 to 5.25V input voltage range has been introduced by Diodes Incorporated. Featuring a low 35μA quiescent current, low RDS(ON) and a six-pin X2 DFN1212 package, the AP7342 is particularly well-suited for compact, low-power, handheld, consumer electronic products such as smart phones, tablets, cameras and portable media players.
