„ Features
The XC6205 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 ~ 1.75V.
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.

! Operational Explanation
Output voltage control with the XC6205 series :
VIN
CE
ON/OFF
Control
The voltage divided by resistors R1 & R2 is compared
with the internal reference voltage by the error amplifier.
each circuit
The P-Channel MOSFET, which is connected to the
VOUT pin, is then driven by the subsequent output
signal. The output voltage at the VOUT pin is controlled
& stabilized by a system of negative feedback.
Current
Limiter
VOUT
R2
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.

Low ESR Capacitors
With the XC6205 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 (CL) is connected as close as possible to the output pin (V OUT) and the VSS pin. Please use an
output capacitor with a capacitance value as shown in the figure below. Also, please connect an input capacitor
(CIN) of 0.1µF between the VIN pin and the VSS pin in order to ensure a stable power input.

0.9V ~ 1.2V

1.25V ~ 1.75V
2.2µF
Current Limiter, Short-Circuit Protection
The XC6205 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. However, when the input/output voltage differential is quite small, this current will be
about 200mA.
CE Pin
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6205 series. In shutdown
mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. The operational logic of the IC's CE
pin is selectable (please refer to the selection guide on page 2). Note that as the standard XC6205B 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 is 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.

Minimum Operating Voltage
In order to stablize the IC's operations, an input voltage of more than 2.0V is needed. Should the input voltage be
less than 2.0V, the output voltage may not be regulated correctly. (Please refer to the graph data below.)
1 When VIN is less than 2.0V, the CE pin remains in standby mode.
When VIN rises above 2.0V, the power supply will turn ON.
2 The input power supply will begin to rise after a few hundred µsec.
(Please also refer to the transient response characteristics.)

! 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 IN and VSS wiring in particular.
3 Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
