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.

240 & 480W DIN-rail supplies address space constraints

240 & 480W DIN-rail supplies address space constraints
Addressing space constraints on TS-35/7.5 or TS-35/15 DIN-rails in the industrial control market, Mean Well has added 240 and 480W models to its NDR-xx series of slim, economical DIN-rail power supplies, measuring 63 and 85.5mm, respectively. The NDR-240 and NDR-480 models feature volumes reduced by 43 and 51.6%, respectively, compared to the previous generation DRP-240/480 series.
