Each of Regulators 1 and 2 is operating with an external PNP transistor as shown in the above figure. Regulators 1 and 2 divide Output Voltage VOUT by Feed-back Registers R1 and R2, and the divided voltage at the node between Registers R1 and R2 is compared with the reference voltage by Error Amplifier, so that the base current of the PNP transistor is adjusted, and a constant voltage is output. The output current from each of Regulators 1 and 2 is monitored by Current Limitter, and when the output current exceeds a limit current, Current Limitter limits the base current of the PNP transistor to the specified limit current. The level of input signals to CSW 1, 2 is set at the same level as the output voltage level of ROUT4 by built-in level shift circuit. Phase compensation is made externally with C1,2.

Step of Operation The following descriptions deal with VDD pin and VSEN1 pin as connected each other, but Detector 1 can be detected the different voltage from VDD through VSEN1 pin.
Step 1. Output Voltage is equal to Pull-up Voltage. Step 2. When Input Voltage (VSEN1)reaches the state of Vref VSEN1 * (Rb+Rc)/(Ra+Rb+Rc)at Point A (Detected Voltage -VDET), the output of Comparator is reversed, so that Output Voltage becomes GND. Step 3. Output Voltage becomes indefinite when Power Source Voltage (VDD) is smaller than Minimum Operating Voltage. When the output is pulledup,VDD is output. Step 4. Output Voltage becomes equal to GND. Step 5. When Input Voltage to (VSEN1) reaches the state of Vref VSEN1 * Rb/(Ra + Rb) at Point B (Released Voltage+VDET), the output of Comparator is reversed, so that Output Voltage becomes equal to Pulled-up Voltage.

Step of Operation The following descriptions deal with VDD pin and VSEN2 pin as connected each other, but Detector 2 can be detected the different voltage from VDD through VSEN2 pin.
Step 1. Output Voltage is equal to Pull-up Voltage. Step 2. When Input Voltage (VSEN2) reaches the state of Vref VSEN2 * (Rb+Rc)/(Ra+Rb+Rc)at Point A (Detected Voltage - VDET), the output of Comparator is reversed, so that Output Voltage becomes GND. Discharging is performed from CD pin connected to External Capacitor. No delay time is generated. Step 3. Output Voltage becomes indefinite when Power Source Voltage (VDD) is smaller than Minimum Operating Voltage. When the output is pulledup,VDD is output. Step 4. Output Voltage becomes equal to GND. Step 5. When Input Voltage (VSEN2) reaches the state of VrefVSEN2 * Rb/(Ra + Rb) at Point B (Released Voltage +VDET), the output of Comparator is reversed, and the External Capacitor is charged through CD pin,so that Output Voltage becomes equal to Pulled-up Voltage after a delay timeTD (= 0.69 x 106 x CD).

TYPICAL APPLICATION
* RV5VE001x
In this example of the circuit, the output of Regulator 4 is used as the power source for CPU. The voltage input to CSW 1, 2, 3 pins is subject to level shift within the IC so as to have the same level as that of the voltage of CPU. Therefore CSW 1, 2, 3 pins can be directly connected to CPU. Detector 1 monitors the voltage of the battery and Detector 2 monitors the voltage of the power source for CPU. Application for Cellular Phones (RV5VE001x)

APPLICATION HINTS
When using these ICs, be sure to take care of the following points : * Minimize the impedance of VDD and GND wiring. In particular, with respect to the VDD wiring, the output current of Regulators flows thereinto, so that when the wiring impedance is high, the operation of the IC tends to be unstable and is vulnerable to noise. * Provide a capacitor with a capacitance of about 10F between VDD pin and GND pin with a minimum wiring length. * Rush current flows into the capacitor connected to the output of Regulators at the start of the operation of the Regulators. In particular, Regulators 1, 2 are equipped with External PNP Transistor and accordingly have excellent drive performance. Therefore, when Regulators 1, 2 start to operate, for example, under the conditions that hFE of External PNP Transistor is 100 and the base current of the limiter is 5mA, a rush current of 500mA flows into the regulators. When the wiring impedance is high, the Power Source Voltage applied to IC tends to be varied by the rush current, so that the operation of IC may be adversely affected by the variation of the Power Source Voltage. * In these ICs phase compensation is made for securing stable operation even when the load current is varied. Select the capacitors C1 to C4 conecting the Pin ROUT1 to ROUT4 with good frequency characteristics and small ESR. * Be sure to connect a resistor with a resistance of about 100k between the base and the emitter for preventing the oscillation. * Set external parts as close as possible to the IC and minimize the connection between the parts and the IC. * When using a capacitor connected to CD pin, use a Schottky Barrier Diode (SBD) to discharge CD capacitor at the time of abrupt fluctuation of power source voltage.

APPLICATION FOR CELLULAR PHONES (RV5VE0xxx:Optional Mask Version)
This Optional Mask Version's application operates as follows. Regulator 1, 2 Regulator 3 Regulator 4 : Regulator 1 and 2 can be enabled and disabled through Toggle Input and CPU signal CSW1. : Regulator 3 can be enabled and disabled through Toggle Input and CPU signal CSW2. : Regulator 4 is always enabled by dry cells (when the VDD voltage is maintained higher than minimum operating voltage). The output of Regulator 4 is not only the power source for CPU but also the level shift voltage of CSW 1, 2 pins. Therefor CSW1, 2 pins can be directly connected to CPU. Detector 1, 2 : Detector 1 and 2 monitor the VDD level and the output of Regulator 4 respectively. Furthermore Detector 2 can generate the output-delay time (time delay to output rising edge) by connecting a capacitor to CD pin. TFF : TFF can be reset by the output of power-on-reset and Detector 2 (through one shot pulse generator), while TFF is in the reset state Regulator 1, Regulator 2 and Regulator 3 are disabled.
