OUTLINE

The R8152x Series are CMOS-based 24 V input voltage regulators featuring 1 A output current and 24 V input

voltage. R8152 provides high input voltage operation and low on-resistance (at VOUT = 10 V, below 0.6 Ω) by

using DMOS*1 transistor. In addition to the basic regulator circuits, R8152x contains an over current protection

circuit, an output short-circuit protection circuit, and a thermal shutdown circuit. Besides the low supply current

by CMOS, the operating temperature is –40

°C to 125°C and the maximum input voltage is 24 V, R8152x is

suitable for power source of car accessories. R8152x is available in fixed output voltage options between 3.0 V

and 12.0 V in 0.1 V steps, and between 12.5 V and 18.0 V in 0.5 V steps. The output voltage accuracy is as high

as ±2%.

R8152x is available in two types of packages: HSOP-6J for high wattage and TO-252-5-P2 for high-density

mounting.

*1 DMOS: Defined as Double Diffused MOS.

DMOS transistor is composed of a low-density n-type (channel) diffused layer and a high-density p-type (sources) diffused

layer from the edge of the gate electrode. By scaling down the channel length to submicron dimensions and also decreasing

the thickness of the gate oxide film, R8152x has been able to achieve outstanding characteristics of high voltage resistance

and low on-resistance.
