MAXIM INTEGRATED PRODUCTS MAX603CSA+ Fixed LDO Voltage Regulator, 2.7V-11.5V in, 320mV Dropout, 5V/500mA out, NSOIC-8The MAX603CSA+ is a 5V or adjustable, low dropout, low IQ, 500mA linear regulator in 8 pin NSOIC package. The typical dropout of 320mV at 500mA(5V), quiescent currents are 15A typ and 35A max. Shutdown turns off all circuitry and puts the regulator in a 2A off mode.

The MAX603CSA+ is a 5V or adjustable, low dropout, low IQ, 500mA linear regulator in 8 pin NSOIC package. The typical dropout of 320mV at 500mA(5V), quiescent currents are 15µA typ and 35µA max. Shutdown turns off all circuitry and puts the regulator in a 2µA off mode. A unique protection scheme limits reverse currents when input voltage falls below output. Other features include foldback current limiting and thermal overload protection. The output is preset at 5V in addition, it employ Dual Mode operation allowing user-adjustable outputs from 1.25V to 11V using external resistors. The input voltage supply range is 2.7V to 11.5V. It features a 500mA P-channel MOSFET pass transistor. This transistor allows device to draw less than 35µA over temperature, independent of the output current. It is used in 5V regulators, 1.25V to 11V adjustable regulators, battery-powered devices, pagers and cellular phones and solar-powered instruments.
- 500mA output current with foldback current limiting
- Operating temperature range from 0°C to 70°C
- High power of 1.8W
- Thermal overload protection
- Reverse current protection
- Dropout voltage of 320mV at Iout=500mA

Gentle soap, great for hands and body!
I love how gentle this oatmeal soap is. It’s perfect for sensitive skin and doesn’t irritate my hands even when they are rough. I keep one at my sink and one in the shower. The natural scent is lovely and not overpowering. A must-buy for those looking for a mild cleanser!

Itchy, red skin BE GONE!
My 94 year old father has recently had a terrible resurfacing of his psoriasis with red, itchy, flaky sores all over his body! It's been so bad that he can't even sleep at night. My heart has been aching for him BUT he is finally getting some relief from this amazing soap!! I just saw him yesterday and, compared to two weeks ago, the redness and itching has lessened considerably. Plus, he loves the way it smells! What a true JOY to know he is on the mend, in part because of this product. I am about to purchase another bar for my sister who suffers the with the same issue. THANK YOU fo making a product that actually does what it claims to do!!!!!!

Great Product
I’ve been using this all-natural eczema soap for the past few weeks, and I’m genuinely impressed by the results. As someone who has struggled with eczema flare-ups for years, I’ve tried countless products, but this soap stands out.
First off, the ingredients are truly natural—no harsh chemicals, fragrances, or preservatives. The soap is made with soothing, skin-friendly components like coconut oil, shea butter, and chamomile extract. It lathers up nicely, creating a gentle, creamy foam that feels luxurious on the skin.
What really stands out is how gentle it is on my sensitive skin. Unlike many other soaps I’ve tried, this one doesn’t dry out or irritate my eczema patches. In fact, it has a calming effect and seems to reduce redness and itching after just a few uses. I’ve noticed that my skin feels softer and more hydrated, which has helped prevent flare-ups.
The scent is mild and pleasant—not overpowering, but just enough to give you a fresh, clean feeling without triggering any sensitivities.
Overall, I’m thrilled with this eczema soap. It’s not only effective at soothing and moisturizing my skin, but it’s also a relief to know that I’m using something that’s completely natural and safe. If you suffer from eczema or other skin sensitivities, I highly recommend giving this soap a try. It’s definitely become a staple in my daily skincare routine.

Expensive, but works if you have a skin condition.
Expensive, but good soap if you have a rash.
