HT78XX — 500mA TinyPower(TM) LDO

Please review product page below for detailed information, including HT price, datasheets, in-stock availability, technical difficulties. And your calculation is extremely optimistic, the ESP ht78833 not consume 82 mA for sending data, it’s more like mA. The data sheet I found shows a current rating of mA. Once I switched to a mA part all the problems went away. We are a strong Community of developers, hackers, and visionaries.

Load regulation is measured at a constant junction temperature, using pulse testing with a low ON time and is guaranteed up to the maximum power dissipation. Have you read it? It turned out to be another application taking o[…].

Further thoughts on power saving: They have low current requirements while idle, but I figured why leave them powered when asleep? Bracketed figures are for consultation only Rev. Submit a new text post. Holtek reserves the right to alter its products without prior hh7833.

Do you need updated data pushed out every 30 seconds? Quickly Enter the access of compare list to find replaceable electronic parts. It has a lower voltage and does not require a regulator to power the esp. Do you know how much if it comes from waking up and establishing a network connection every 30 seconds? Also, the ESP does not run in milliamps when in deep sleep.

Log in or sign up in seconds. Added info below and revised the lifetime from 24 to 12 days, because the cutoff for 2 batteries is 5v not 2. Thanks for the tip! It’s capable of running on 0.

They are available with several fixed output voltages ranging from 1. Since my other projects involve current hungry led strips, I’m probably sticking to LiIon for now. The key to long battery life in any embedded application is designing your application properly, and at the top of the list there to take full advantage of sleep modes. Check out a LiFePO4 cell instead of the lithium ion cells.

The guaranteed specifications apply only for the test conditions listed. We also have a discord serverjoin the live discussion on lots of different topics. Still a big improvement over not sleeping at all I guess, but it won’t last years.

The new type of capacitor has a space-saving datasjeet with two, three or even ten identical capacitors connected in parallel on the same terminal to increase the capacitance. This is what I found on AGM batteries: Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits.

These rechargeable batteries do discharge by themselves rather quickly. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability. Make sure to add a 47uF capacitor at the HT output, it will help.

Htt7833 that I can gauge device lifetime based on cycle frequency and available battery capacity. A bit over a year.
