Vidatronic’s capacitor-less low dropout (LDO) voltage regulators are the best in the industry.
We can provide best-in-class dynamic performance and highest power supply rejection in the industry, all without the use of an external capacitor.
This patented technology provides the opportunity to reduce the total solution board area by approximately 25%, making our solutions the optimum choice for smart phones, Internet of Things (IoT) and wearable devices, and many other applications where board area is a premium.
If saving space while improving performance isn’t enough, we will also lower your overall system costs.
VIDATRONIC LDO VOLTAGE REGULATOR PRODUCT LINES
We have two main product lines for our capless LDOs: the Noise Quencher® and Power Quencher™. Our Noise Quencher® line of LDOs focus on maintaining excellent power supply rejection (PSR) while our Power Quencher™ LDOs feature extremely low quiescent currents, excellent for Internet of Things (IoT) and wearable applications. Within the Power Quencher™ Product Line, we also have an even lower power version of the LDO, the Power Quencher™-LP. For information on licensing our Noise Quencher® or Power Quencher™ architectures, please visit the links below.
WHAT MAKES OUR CAPLESS LDOS UNIQUE
Traditional capless voltage regulator solutions suffer many drawbacks. First, they do not work if there is too much capacitance at the output. If the load capacitance is too large, the LDO will oscillate, meaning the LDO will not work. All System-on-a-Chip (SOC) applications will have some level of load capacitance for the LDO. If the LDO can’t support the output capacitance, the SOC will not function. Secondly, in traditional capless LDOs, the performance without a capacitor is not good enough for practical applications. This means that while the LDOs will function, they will not perform to the correct specifications, which ultimately means that the LDOs are useless in most devices. Lastly, they exhibit poor load/line transient performance and poor power supply rejection, further creating issues when integrated into any electrical designs.
Vidatronic’s Capless LDOs eliminate these issues because while they perform well without a capacitor, they can also support ANY load capacitance, therefore they will work in ANY SOC. Our LDOs also have excellent load/line transient performance and excellent power supply rejection with ANY load capacitance, including NO load capacitance.
