The XC6423 is the latest generation of dual channel CMOS LDO Regulators from Torex Semiconductor.
Comprising two independent LDO circuits, each able to deliver 300mA, the XC6423 offers designers maximum functionality in the smallest possible space.
Measuring only 1.2mm x 1.2mm x 0.4mm, the LGA-6A01 is the latest in a long line of ultra small packages from Torex. It utilises a new construction technique, removing the need for traditional bonding wires in favour of direct connection between die and pads. This allows for significant improvements in thermal performance resulting in higher power dissipation when compared with traditional packaging techniques.
The LGA-6A01 package construction offers benefits in other areas as well. By removing the need for bonding wires between the die and pad we also reduce the total resistance between the input and output pins of the LDO by an appreciable amount. As a result the XC6423’s drop-out voltage is typically only 95mV@150mA (VOUT=3.0V) which helps to extend usable battery life in portable electronic devices.
Ultra fast transient response ensures the highest level of output stability and furthermore, each LDO circuit is completely isolated to ensure no unwanted cross-talk between channels during load fluctuations. The XC6423 delivers high PSRR (75dB@1kHz) and low noise operation making it ideal for both RF and Digital applications.
