Texas Instruments ebook – LDO Basics
https://www.electronics-lab.com/texas-instruments-ebook-ldo-basics/
Power management is a fundamental block for all electronic systems. Without it, smartphones, computers and many other electronics we know today would not be possible. With the additional portability, computational power and the myriad of sensors implemented today comes the necessity to scrutinize power management design. The influx of scrutiny for power designs to meet […]
Torex launches positive voltage LDO regulators based on CMOS
https://www.electronics-lab.com/torex-launches-positive-voltage-ldo-regulators-based-cmos/
The XD6506 is a series of voltage regulators from Torex Semiconductor that is manufactured using CMOS processes. The positive voltage LDO regulators are qualified to AEC-Q100 Grade 2. The regulators achieve low supply current, 0.8 microA (typical) and consist of a reference voltage source, an error amplifier, a current fold-back circuit, and a phase compensation […]
Connecting LDOs in parallel
https://www.electronics-lab.com/connecting-ldos-parallel/
App note from ROHM semiconductor on combining LDOs for higher load capacity. When you want to increase the output current capacity of an LDO, or when the power dissipation of a single LDO is insufficient, you might think of connecting LDOs in parallel if you need to disperse the dissipation using two LDOs. This application […]

Versatile And Open Source LiPo bBattery Breadboard Power Supply
https://www.electronics-lab.com/versatile-open-source-lipo-bbattery-breadboard-power-supply/
Orlando Hoilett from Calvary Engineering LLC designed a versatile Li-Po battery breadboard power supply and wrote an Instructables on it. This power supply outputs 3.3V to the breadboard and takes input from a single-cell LiPo battery. The breadboard power supply also has the ability to charge the battery without needing to separate it from the circuit board. More importantly, this […]

Benefits of Using A Buck-Boost Converter As A Pre-regulator For LDOs
https://www.electronics-lab.com/benefits-using-buck-boost-converter-pre-regulator-ldos/
Intersil published a new white paper titled “Preventing Subsystem Brownouts in Mobile Devices“. This white paper demonstrates the benefit of using a buck-boost converter as a pre-regulator, which leads to better overall system efficiency and enhanced battery life. Systems powered from a battery may have voltage brownout when they are subjected to a burst current […]
How to Improve Buck Converter Light Load Efficiency with an LDO
https://www.electronics-lab.com/improve-buck-converter-light-load-efficiency-ldo/
By Michael Hartshorne @ digikey.com: Designing a DC/DC converter that only consumes micro amps of current at no load can be compared to fueling a muscle car with lighter fluid – you may get it to work, but it won’t be easy. High efficiency at full load currents is commonplace in most modern DC/DC converters; […]
