USP4 – XC6213
Description
High Speed LDO Regulators, Ultra Small Package
The XC6213 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The series achieves high ripple rejection and low dropout and consists of a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor.
Output voltage is selectable in 0.05V increments within a range of 1.2V ~ 5.0V. The series is also compatible with low ESR ceramic capacitors, which give added output stability. The current limiter’s foldback circuit also operates as a short protect for the output current limiter and the output pin.
The CE function enables the output to be turned off, resulting in greatly reduced quiescent current.
