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

=0.1mA 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)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.
