Series
■GENERAL
DESCRIPTION
ETR0306_003
High Speed LDO Regulators Low ESR Cap.Compativle,Output ON/OFFControl
The XC6209/XC6212 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 50mV increments within a range of 0.9V ~ 6.0V.
The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be
maintained even during load fluctuations due to the excellent transient response of the series. 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 power consumption.

*The dissipation pad for the USP-6B
package should be solder-plated in
recommended 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

pin.
