XCM406 Series
700mA High Speed Dual LDO Regulator
GENERAL DESCRIPTION
The XCM406A series is a high current, dual LDO regulator in an ultra small USP-12B01 package which measures just 2.8mm x
2.3mm. The IC is basically two XC6210 high speed CMOS LDOs which are precise, low noise, high current, regulators consisting of a voltage reference, an error amplifier, a current limiter and phase compensation circuit plus a driver transistor. The low ON resistance of the built-in driver transistor means that batteries can be used to a minimal input-output voltage differential and can therefore be used for a longer time. The series can be used with low ESR ceramic capacitors and output voltages are selectable in 0.05V increments within a range of 0.8V to 5.0V per channel. The fold-back current limit circuit also operates as the output current limiter and the output pin protector. The IC can be placed in stand-by mode via the CE function so that power consumption is greatly reduced.

OPERATIONAL EXPLANATION
The voltage, divided by resistors R1 & R2, which are connected to the V
voltage by the error amplifier. The P-channel MOSFET connected to the V output signal. The output voltage at the V current limit circuit and short circuit protection operate in relation to the level of output current.
<Low ESR Capacitor>
With the XCM406 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 (C pin. Please use an output capacitor (C capacitor (C

<Current Limiter, Short-Circuit Protection>
The XCM406 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 drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows. 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
<EN Pin>
The IC's internal regulator circuitry can be shut down via the signal from the EN pin with the XC6210 series. In shutdown mode, output at the V EN pin logic (See the product classification). Note that as the XCM406AA types are 'High Active / No Pull-Down', operations will become unstable with the EN pin open. Although the EN 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 V correct specifications for the EN 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 V
NOTES ON USE
1. Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising phenomenon, 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 fluctuation or load fluctuation occurs, please increase the capacitor value such as C
4. The two dies in the same package are closely placed so that one heat generation affects the other. Heat dissipation should be evaluated on the actual board design before finalizing. In case of light load operation like 100μA below, but the other side is heavy load operation, the light load output voltage may happen to be elevated up to the input voltage level as a result of leakage current. As a counter measure when it happened, adding one resistor between V
and VSS pins is recommended.
