ME6207 High Output Current LDO Regulator , High PSRR , Low Dropout, ME6207 Series General Description Features The ME6207 Series is a positive voltage regulator with a low dropout voltage,high output voltage accuracy,and low crrent consumption developed based on CMOS technology. A built-in low on-resistance transistor provides a low dropout voltage and large output current, a built-in overcurrent protector prevents the load current from exceeding the current capacitance of the output transistor. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the conventional CMOS process, a larger variety of capacitors are available, including small ceramic capacitors.

Basic operation Figure 1 shows the block diagram of the ME6207 Series. The error amplifier compares the reference voltage (Vref) with Vfb, which is the output voltage resistance-divided by feedback resistors Rs and Rf. It supplies the output transistor with the gate voltage necessary to ensure a certain output voltage free of any fluctuations of input voltage and temperature. Figure 1 2. Output transistor The ME6207 Series uses a low on-resistance P-channel MOS FET as the output transistor.Be sure that VOUT does not exceed VIN + 0.3 V to prevent the voltage regulator from being damaged due to inverse current flowing from VOUT pin through a parasitic diode to VIN pin. 3. Shutdown pin (CE pin) This pin starts and stops the regulator. When the CE pin is set to the shutdown level, the operation of all internal circuits stops, and the built-in P-channel MOS FET output transistor between the VIN pin and VOUT pin is turned off to substantially reduce the current consumption. The VOUT pin becomes the VSS level due to the internally divided resistance of several hundreds kΩ between the VOUT pin and VSS pin. Since the CE pin is neither pulled down nor pulled up internally, do not use it in the floating state. In addition, note that the current consumption increases if a voltage of 0.3 V to VIN − 0.3 V is applied to the CE pin.

Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low.When mounting an output capacitor between the VOUT and VSS pins (CL) and a capacitor for stabilizing the input between VIN and VSS pins (CIN), the distance from the capacitors to these pins should be as short as possible. 2.Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or less). 3.Generally a series regulator may cause oscillation, depending on the selection of external parts. The following conditions are recommended for this IC. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Input capacitor (CIN): 4.7 µF or more Output capacitor (CL): 4.7 µF or more Equivalent series resistance (ESR): 0.5 Ω or less 4. The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small or an input capacitor is not connected. 5.The application conditions for the input voltage, output voltage, and load current should not exceed the package power dissipation. 6. Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. 7.
