5 TARSU~TARSU Application Note. Recommended Application Circuit V IN V OUT μf μf Control Level HIGH Operation ON CONTROL GND. μf NOISE LOW OFF The noise capacitor should be connected to NOISE pin to GND for stable operation. The recommended value is higher than.7 μf. The figure above shows the recommended configuration for using a point regulator. Insert a capacitor for stable input/output operation. If the control function is not to be used, Toshiba recommend that the control pin (pin ) be connected to the V CC pin.. Power Dissipation The power dissipation for board-mounted TARSxxU Series devices (rated at mw) is measured using a board whose size and pattern are as shown below. When incorporating a device belonging to this series into your design, derate the power dissipation as far as possible by reducing the levels of parameters such as input voltage, output current and ambient temperature. Toshiba recommend that these devices should typically be derated to 7%~8% of their absolute maximum power dissipation value.

6 . Ripple Rejection TARSU~TARSU The devices of the TARSxxU Series feature a circuit with an excellent ripple rejection characteristic. Because the circuit also features an excellent output fluctuation characteristic for sudden supply voltage drops, the circuit is ideal for use in the RF blocks incorporated in all mobile telephones. 8 Ripple Rejection f TARS8U Input Transient Response 7 Ripple rejection (db) μf. μf μf VIN =.

V, Iout = ma Frequency f (Hz) Time t (ms). NOISE Pin TARSxxU Series devices incorporate a NOISE pin to reduce output noise voltage. Inserting a capacitor between the NOISE pin and GND reduces output noise. To ensure stable operation, insert a capacitor of.7 μf or more between the NOISE pin and GND. The output voltage rise time varies according to the capacitance of the capacitor connected to the NOISE pin.

7 . Example of Characteristics when Ceramic Capacitor is Used TARSU~TARSU Shown below is the stable operation area, where the output voltage does not oscillate, evaluated using a Toshiba evaluation circuit. The equivalent series resistance (ESR) of the output capacitor and output current determines this area. TARSxxU Series devices operate stably even when a ceramic capacitor is used as the output capacitor. If a ceramic capacitor is used as the output capacitor and the ripple frequency is khz or more, the ripple rejection differs from that when a tantalum capacitor is used. This is shown below. Toshiba recommend that users check that devices operate stably under the intended conditions of use.
