■FEATURES
■GENERAL DESCRIPTION
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 50mV increments
within the range of 0.8V to 5.0V.
Maximum Output Current
: More than 700mA
(800mA limit, TYP.)
(1.6V<VOUT(T)<5.0V)
: 50mV@IOUT=100mA
: 1.5V ~ 6.0V

Output Voltage Range
: 0.8V ~ 5.0V
(50mV increments)
: +2%
(The setting voltage accuracy)
: 35µA (TYP.)
: 60dB @1kHz
Highly Accurate
Low Power Consumption
High Ripple Rejection
Operational Ambient Temperature
: - 40℃ ~ 85℃
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 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 VSS pins.

■OPERATIONAL EXPLANATION
<Output Voltage Regulator Control>
The voltage, divided by resistors R1 & R2, which are connected to the VOUT pin 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 VOUT pin is controlled & stabilized by negative feedback. The
constant current limit circuit and short circuit protection operate in relation to the level of output current.
<Low ESR Capacitor>
With the XC6210 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase
compensation circuit is built into the regulator. In order to ensure the effectiveness of the phase compensation, we
suggest that an output capacitor (CL) be connected as close as possible, between the output pin (VOUT) and the VSS pin.
Please use an output capacitor (CL) with a capacitance, based on the chart below. We also suggest an input capacitor
(CIN) of 1µF: this should be connected between VIN and VSS in order to stabilize input power source.

<Current Limiter, Short-Circuit Protection>
The XC6210 series regulator offers a combination of current limit and short circuit protection by means of a built-in fixed
current limiter circuit and a foldback circuit. 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,
the 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 regulator circuitry can be shut down via the signal from the CE pin with the XC6210 series. In
shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. Options are available for the
CE pin logic (See the product classification). Note that as the XC6210B types are '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 if a voltage other than VIN or VSS is applied.
■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 VIN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. Should rapid input
fluctuation or load fluctuation occur, please increase the capacitor value such as CIN or CL to stabilize the operation.
