Hi, I need to apply the virtual EEPROM on a RA2E1. In principle, this mechanism works, and I can write and read the record IDs. During the production of the board, I need to program the original content of this rec id. ...Read more
Hello, The SMPS reduces the power loss when VDD is regulated down to the core voltage with an internal LDO. The SMPS, thus, increases energy effectiveness. However, you're better off with the LDO version because you have further GPIOs and one lower coil and capacitor on the BOM, If you do not need tRead more
Hello,
The SMPS reduces the power loss when VDD is regulated down to the core voltage with an internal LDO. The SMPS, thus, increases energy effectiveness.
However, you’re better off with the LDO version because you have further GPIOs and one lower coil and capacitor on the BOM, If you do not need to save every milliwatt.
Does it answer your question?

Hello@vikas, It's always recommended to use a bleeder of 100 ohms. Vout of the part has an offset of around 250mV due to a leakage in no-load condition. The 100-ohm bleeder will pull it down. If there's no issue with 250mV offset the part can be used without bleeder also. If there's a concern with eRead more
Hellovikas Nagpal,
It’s always recommended to use a bleeder of 100 ohms.
Vout of the part has an offset of around 250mV due to a leakage in no-load condition.
The 100-ohm bleeder will pull it down.
If there’s no issue with 250mV offset the part can be used without bleeder also.
If there’s a concern with effectiveness while using a 100-ohm bleeder also a 500-ohm bleeder can be used. 500-ohm bleeder will have an offset of 65mV.
