XC6210 Series

High Speed LDO Regulators

The XC6210 series are precise, low noise, high current, positive voltage low dropout regulators. They are fabricated using Torex's CMOS process. The series features a voltage reference, an error amplifier, a current limiter, and a phase compensation circuit plus a driver transistor.

With a low ON resistance driver transistor built-in, batteries can be used until input-output voltage differential is minimal and can accordingly be used for a longer time. The series is also compatible with low ESR ceramic capacitors which give added output stability. The output voltage of the LDO and detect voltage of the detector is selectable in 0.05V increments within the range of 0.8V to 5.0V. The current limiter's foldback circuit also operates as the output current limiter and the output pin protection.

The IC's internal regulator circuit can be placed in stand-by mode via the CE function. In the stand-by mode, quiescent current is greatly reduced.

QuestionWhat is the standby current?

The current that flows through the IC in the standby mode. The standby mode means the state where the IC has been turned off by the CE function.
