Transcription

1 SERIES Low on Resistance / Low Voltage 1A LDO NO.EA OUTLINE The RP132x Series are voltage-regulators with a built-in low ON-resistance transistor and output current is 1A capability. These ICs have two versions: fixed output voltage type and externally adjustable output voltage type. The minimum output voltage can be set from 1.4V. Otherwise, the load regulation of RP132x has much improved when compared with conventional regulators. It's Typ.5mV at IOUT=.1mA to 1A. Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor net for setting output voltage, current limit circuits to prevent over-current and a thermal-shutdown circuit. A standby mode with ultra low supply current can be realized with the chip enable function. Additionally, E/F Version with delay pin for inrush current limit time setting are also available. The packages for these ICs are DFN(PLP)182-6, SOT-89-5, HSOP-6J and TO P2. DFN(PLP)182-6 is suitable for high density mounting of the ICs on boards. SOT-89-5, HSOP-6J and TO P2 are supporting high wattage. FEATURES Output Current... Min. 1A Supply Current... Typ. 65μA Standby Current... Typ..15μA Input Voltage Range V to 6.5V Range...

Also refer to "Inrush Current Limit Time Settings" concerning with CD. TECHNICAL NOTES When using these ICs, consider the following points: Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a capacitor with good frequency characteristics and ESR (Equivalent Series Resistance). If a tantalum capacitor is used, and its ESR of is large, the loop oscillation may result. Because of this, select carefully considering its frequency characteristics. PCB Layout Make and lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor between and pin with a capacitance value as "Recommendation value of the external capacitors" above or more, and as close as possible to the pins. Set external components, especially the output capacitor, as close as possible to the ICs, and make wiring as short as possible. 13

For this purpose, use a 4.7μF or more capacitor between pin and pin, and as close as possible to the pins. PCB Layout Make and lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor with a capacitance value as much as 2.2μF or more between and pin, and as close as possible to the pins. When using the Adjustable Type, the transient response could be affected by the external resistors. Evaluate the circuit taking the actual conditions of use into account. 14

15 Adjustable Type Settings Setting Method RP132x81x can be adjusted the output voltage up to 5.5V by using the external divider resistors. Also, please use 16kΩ or less for R2 resistor. If the voltage is described as set, the output voltage can be set by using the following equations Set is equal to.8v. The pin of RP132x81x should be connected to the pin. R1 I1 RIC IIC R2 I2 Set I1= IIC + I2...(1) I2= set / R2...(2) Thus, I1= IIC + set /R2...(3) Therefore, = set R1 I1...(4) Put Equation (3) into Equation (4), then = set + R1(IIC + set / R2) = set (1+R1/ R2) + R1 IIC...(5) In Equation (5), R1x IIC is the error-causing factor in. As for IIC, IIC = set / RIC...(6) Therefore, the error-causing factor R1x IIC can be described as follows. R1 IIC = R1 set / RIC = set R1 / RIC...(7) For better accuracy, choosing R1 (<<RIC) reduces this error. Without the error-causing factor R1x IIC, the output voltage can be calculated by the following equation = set ((R1 + R2) / R2)...(8) RIC of RP132x is approximately Typ.1.3MΩ(Topt=25 C, this value is guaranteed by design.). The value could be affected by the temperature, therefore evaluate the circuit taking the actual conditions of use into account. 15

16 Inrush Current Limit Time Settings The RP132xSeries include the circuit which can limit the inrush current at start-up to 5mA or less. The current limit time of B/D version is fixed internally as approximately Typ.5μs. On the other hand, the current limit times of E/F versions are adjustable by controlling the pin value, which is the capacitance value connected between DLEAY pin and pin. The relation between Inrush Current Limit Time (t D [s]) and the pin capacitance (C D [F]) can be described in the following equation. td=(cd ) When not using CD on E/F versions, pin should be open. In this case, C D = is applied to the above equation and as a result, 37μs can be obtained. That means, when using C D on E/F versions, the inrush current limit time will be more than 37μs. Please note that during the inrush current limit time, the load current cannot be more than the limited current. 16

34 ESR vs. Output Current When using these ICs, consider the following points: The relations between IOUT (Output Current) and ESR of an output capacitor are shown below. The conditions when the white noise level is under 4μV (Avg.) are marked as the hatched area in the graph. Measurement Conditions Frequency Band : 1Hz to 2MHz Temperature : 4 C to 85 C Hatched Area : Noise level is under 4μVms (Avg.)

35 Halogen Free For the conservation of the global environment, Ricoh is advancing the decrease of the negative environmental impact material. After Apr. 1, 26, we will ship out the lead free products only. Thus, all products that will be shipped from now on comply with RoHS Directive. Basically after Apr. 1, 212, we will ship out the Power Management ICs of the Halogen Free products only. (Ricoh Halogen Free products are also Antimony Free.)
