High Speed LDO Regulators Low ESR Cap.Compatible,Output ON/OFFControl
GENERAL DESCRIPTION
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.

PIN NAMEFUNCTION
*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
SS pin.

XC6209/XC6212Series
OPERATIONAL EXPLANATION
<Low ESR Capacitors>
With the XC6209/6212 series, a stable output voltage is achievable even if used with low ESR capacitors as a phase
compensation circuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that an
output capacitor (C
output capacitor with a capacitance value of at least 1μF. Also, please connect an input capacitor (C
between the V
Stable phase compensation may not be ensured if the capacitor runs out capacitance when depending on bias and
temperature. In case the capacitor depends on the bias and temperature, please make sure the capacitor can
ensure the actual capacitance.
<Current Limiter, Short-Circuit Protection>
The XC6209/6212 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the
operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed
current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit
operates, output voltage drops further and output current decreases. When the output pin is shorted, a current of
about 50mA flows.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6209/6212 series. In shutdown
mode, output at the V
is selectable (please refer to the selection guide). Note that as the standard XC6209/6212B type is ' High Active/No
Pull Down', operations will become unstable with the CE pin open. Although the CE pin is equal to an inverter input
with CMOS hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the
IC’s in operation.
We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with
the correct specifications for the CE pin, the IC will operate normally. However, supply current may increase as a
result of through current in the IC's internal circuitry
NOTES ON USE
1 Please use this IC within the stated absolute maximum ratings.
The IC is liable to malfunction should the ratings be exceeded.
2 Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on
output current. Please strengthen V
3 Please wire the input capacitor (C
L) is connected as close as possible to the output pin (VOUT) and the VSS pin. Please use an
IN pin and the VSS pin in order to ensure a stable power input.
OUT pin will be pulled down to the VSS level via R1 & R2. The operational logic of the IC's CE pin

IN) and the output capacitor (CL) as close to the IC as possible.
Output voltage control with the XC6209/6212 series:
The voltage divided by resistors R1 & R2 is compared with the
internal reference voltage by the error amplifier.
The P-channel MOSFET, which is connected to the VOUT pin, is
then driven by the subsequent output signal. The output voltage at
the V
OUT pin is controlled & stabilized by a system of negative
feedback.
The current limit circuit and short protect circuit operate in relation
to the level of output current. Further, the IC's internal circuitry can
be shutdown via the CE pin's signal.
