RP132x Series
AEC-Q100 Compliant
Low on Resistance / Low Voltage 1 A LDO for Automotive Applications
NO.EC-265-190408
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 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 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 SOT-89-5, HSOP-6J and TO-252-5-P2. They range from high-density mounting
to ultra high wattage.

* 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.
