RP132x SERIES
Low on Resistance / Low Voltage 1A LDO
NO.EA-265-110727
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
=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 DFN1616-6B and DFN(PLP)1820-6 which are suitable for high density
mounting of the ICs on boards. SOT-89-5, HSOP-6J and TO-252-5-P2 with high wattage dissipation are also
available.
