RP132x SERIES Low Voltage 1A Voltage Regulator (LDO Regulator) NO.EA-265-171220 OUTLINE The RP132x is a voltage-regulator with a built-in low ON-resistance transistor and output current is 1A capability. This IC has 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=0.1mA to 1A. This IC 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)1820-6, SOT-89-5, HSOP-6J and TO-252-5-P2. DFN(PLP)1820-6 is suitable for high density mounting of the ICs on boards. SOT-89-5, HSOP-6J and TO-252-5-P2 are supporting high wattage.

Also refer to "Inrush Current Limit Time Settings" concerning with CD. Technical Notes on the External Components When using this IC, consider the following points: Phase Compensation In this IC, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a 4.7µF or more capacitor COUT between VOUT pin and GND pin, and as close as possible to the pins. If a tantalum capacitor is used, and its ESR (Equivalent Series Resistance) of COUT is large, the loop oscillation may result. Because of this, select COUT carefully considering its frequency characteristics. PCB Layout Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a 2.2 µF or more capacitor CIN between VDD and GND 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 COUT, as close as possible to the IC, and make wiring as short as possible. When using the Adjustable Output Voltage Type, the transient response could be affected by the external resistors. Evaluate the circuit taking the actual conditions of use into account. Output Voltage Setting Method (Adjustable Output Voltage Type) RP132x081x 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 VFB voltage is described as setVFB, the output voltage can be set by using the following equations. SetVFB is equal to 0.8V. The VOUT pin of RP132x081x should be connected to the VFB pin. 13 RP132x NO.EA-265-171220 VOUT R1 I1 VFB VOUT IIC RIC R2 I2 SetVFB GND I1= IIC + I2 .......................................................................................................................................
