XC6210
Series
High Current, High Speed LDO Regulators
ETR0317_007
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 into, 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 is selectable in 0.05V increments within the range of 0.80V to 5.00V.
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, power
consumption is greatly reduced.

*The dissipation pad for the USP-6B package should be solder-plated in reference mount
pattern and metal masking so as to enhance mounting strength and heat release. If the pad
needs to be connected to other pins, it should be connected to the V
