R1501x SERIES

1A LDO REGULATOR (Operating Voltage up to 24V)

NO.EA-184-160801

OUTLINE

The R1501x series are CMOS-based positive voltage regulator (VR) ICs. The R1501xxxxB has features of high

input voltage operating, 1A output current drive, and low supply current.

ADMOS transistor is used for the driver, high voltage operating and low on resistance (0.6Ω at V^OUT=10V) device

is realized. A standard regulator circuit with a current limit circuit and a thermal shutdown circuit are built in the

R1501x series.

As the operating temperature range is from -40°C to 105°C and maximum input voltage is up to 24V, the R1501x

series are suitable for the constant voltage source for digital home appliances and car accessories.

The regulator output voltage is fixed in the R1501x. Output voltage accuracy is ±2.0% and output voltage range

is from 3.0V to 12.0V with a step of 0.1V, and from 12.5V to 18.0V with a step of 0.5V. The chip enable pin realizes

ultra low supply current standby mode.

Since the packages for these ICs are the HSOP-6J for high density mounting of the ICs on boards, and the TO-

252-5-P2.

∗) The DMOS (Double Diffused MOS) transistor adopted by R1501x is characterized by a double diffusion structure which

comprises a low density n-type (channel) diffused layer and a high density p-type (sources) diffused layer from the edge

of the gate electrode. The R1501x series possess outstanding properties of high operating voltage and low on-resistance,

which have been achieved by the channel length scaled down to submicron dimensions and decreased thickness of the

gate oxide film.
