10 / 27 page 10/27 XC6213 Series SETTING VOLTAGE 1.2 ~ 1.75V 1.8 ~ 5.0V CL More than 3.3μF More than 1.0μF ■ OPERATIONAL EXPLANATION ■ NOTES ON USE <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 current limit circuit and short circuit protection operate in relation to the level of output current. Further, the voltage regulator's internal circuitry can be shutdown via the CE pin's signal. <Low ESR Capacitor> With the XC6213 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase compensation circuit is built-in to the regulator. In order to ensure the effectiveness of the phase compensation, please connect an output capacitor (CL) with a capacitance, based on the chart below. The equivalent serial resistor (ESR) of the output capacitor (CL) should be within the range as the graph below shown. We also suggest an input capacitor (CIN) of 1.0 µF: this should be connected between VIN and VSS in order to stabilize input power source. Output Capacitor Corresponding Chart <Short-Circuit Protection> The XC6213 series regulator offers circuit protection by means of a built-in 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 XC6213 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level. Note that as the XC6213B types are 'High Active / No Pull-Down', operations will become unstable with the CE pin open. 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. <Minimum Operating Voltage> Please apply input voltage more than 2.0V or more in order to stabilize the operation of the IC’s. Normal output voltage may not be obtained when the input voltage is lower than 2.0V. 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. 4. Make sure not to use the IC with large current at high temperature. When exceeding power dissipation of a package, heat occurs before short protection operates, and the IC may break.
