How to choose LDO capacitance and noise in LDO and DC/DC

Electronic Enthusiasts Network reported (text / Li Ningyuan) The output voltage conditions of traditional linear regulators are very strict, and this is the birth of LDO-type voltage conversion chips. In LDO selection and design, it is often difficult. First we have to consider not only the type and range of the input voltage, such as […]

Buck Switching Regulators and LDOs in Industrial and Automotive Applications

Autonomous control is extremely common in both industrial and automotive applications, and many autonomous controls rely on current loops. Taking industrial applications as an example, current loops are ubiquitous in control loops that work in both directions. The loop transmits the measured values ​​from the sensor to the programmable logic controller PLC, which in turn […]

The bilinear regulator of Digital IC power supply can realize real-time output adjustment and dynamic margin optimization

Usually, LDO regulators need to modify the hardware to adjust their output voltage, but if the specification changes constantly, the changes of circuit boards and components may increase a lot of development time. In such applications, LDO regulators with software programmable output voltage can save time and cost. However, the software control of LDO regulator […]

Some little-known aspects of designing with LDO

Low dropout linear regulator (LDO) is ubiquitous in circuit design. Many have only three terminals; VIN, Vout and GND. What could go wrong? Some LDO design criteria have been fully demonstrated, such as the need to observe the correct output capacitance and equivalent series resistance (ESR). Modern LDOS make this easier because they support a […]
