RP132x-Y Series
Low on Resistance / Low Voltage 1 A LDO for High Temperature Applications
NO.EA-343-190408
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 externally adjustable output voltage type is adjustable between 0.8V and 5.5V. The minimum input voltage
can be set from 1.4V. Otherwise, the load regulation of RP132x has much improved when compared with
conventional regulators. It is Typ.5mV at I
OUT
½0.1mA
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.
The packages for these ICs are DFN(PLP)1820-6, SOT-89-5, HSOP-6J, and TO-252-5-P2. They range from
high-density mounting to ultra high wattage.

The
auto discharge function at off state options are as follows.
(B) without auto discharge function* at off state
(D) with auto discharge function* at off state
* 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.
