RP132x SERIES Low Voltage 1A Voltage Regulator (LDO Regulator) NO.EA-265-190408 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.

The voltage in 0.05 V step is shown as follows: Ex. 1.05 V : RP132x101x5 Contact our sales representatives for other voltages. The combination of the auto discharge function and delay pin (for setting inrush current limit time) are as follows. B: without auto discharge function D: with auto discharge function E: without auto discharge function, with delay pin (for setting inrush current limit time) F: with auto discharge function and delay pin (for setting inrush current limit time) The auto discharge function at off state are options as follows. B: without auto discharge function at off state D: with auto discharge function at off state (1) Auto-discharge function quickly lowers the output voltage to 0V, when the chip enable signal is switched from the active mode to the standby mode, by releasing the electrical charge accumulated in the external capacitor. 2
