R1161x SERIES 3-MODE 300mA LDO REGULATOR NO.EA-106-130415 OUTLINE The R1161x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, and low ON-resistance. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit. These ICs perform with low dropout voltage and a chip enable function. To prevent the destruction by over current, current limit circuit is included. The R1161x Series have 3-mode. One is standby mode with CE or standby control pin. Standby mode realizes ultra small consumption current off mode. Other two modes are realized with ECO pin. Fast Transient Mode (FT mode) and Low Power Mode (LP mode) are alternative with ECO pin. Consumption current is reduced at Low Power Mode compared with Fast Transient Mode. Output voltage is maintained between FT mode and LP mode. The output voltage of these ICs is internally fixed with high accuracy. Since the packages for these ICs are SOT-23-5, SON-6 (Non-promotion), and HSON-6 (Non-promotion), high density mounting of the ICs on boards is possible.

ABSOLUTE MAXIMUM RATINGS Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the life time and safety for both device and system using the device in the field. The functional operation at or over these absolute maximum ratings is not assured. RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 5 R1161x ELECTRICAL CHARACTERISTICS * R1161xxxxA Symbol Topt=25C Item Output Voltage (FT Mode) VOUT Output Voltage (LP Mode) IOUT VOUT/ IOUT VOUT/ IOUT VDIF Output Current Load Regulation (FT Mode) Load Regulation (LP Mode) Dropout Voltage ISS1 Supply Current (FT Mode) ISS2 Supply Current (LP Mode) Istandby Supply Current (Standby) VOUT/ VIN Line Regulation (FT Mode) VOUT/ VIN Line Regulation (LP Mode) RR Ripple Rejection (FT Mode) VIN VOUT/ Topt Ilim RPU RPD VCEH VCEL VEN Input Voltage Output Voltage Temperature Coefficient Short Current Limit CE Pull-up Resistance ECO Pull-down Resistance CE , ECO Input Voltage "H" Conditions Typ.

TECHNICAL NOTES VDD C1 OUT R1161xxxxx GND SERIES CE C2 ECO When using these ICs, consider the following points: 1.Mounting on PCB Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor C1 with as much as 1.0F capacitor between VDD and GND pin as close as possible. Set external components, especially the output capacitor as close as possible to the ICs and make wiring as short as possible. 2.Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, be sure to use a 1.0F more capacitor C2 with good frequency characteristics and ESR (Equivalent Series Resistance). Output Voltage VOUT<1.0V 1.0V < = VOUT Recommended Value of C2 1.0F or more Tantalum Capacitor 1.0F or more Ceramic Capacitor (Note: When the additional ceramic capacitors are connected to the Output Pin with Output capacitor for phase compensation, the operation might be unstable. Because of this, test these ICs with as same external components as ones to be used on the PCB.) If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable. Evaluate your circuit with considering frequency characteristics. Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature characteristics are different. Evaluate the circuit with actual using capacitors. 34 R1161x ESR vs. Output Current When using these ICs, consider the following points: In these ICs, phase compensation is made for securing stable operation even if the output current is varied. For this purpose, be sure to use a capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance) in the range described as follows: The relations between IOUT (Output Current) and ESR of Output Capacitor are shown below. The conditions when the white noise level is under 40V (Avg.) are marked as the hatched area in the graph.
