R1500x Series

500mA 24V Input VR

The R1500x Series are CMOS-based voltage regulators featuring 500mA output current and 24V input voltage. R1500x provides high

input voltage operation and low on-resistance (at V^OUT= 10V, below 0.6Ω) because of using CMOS transistor. In addition to a fold-back

protection circuit built into conventional regulators, R1500x contains a thermal shutdown circuit. Besides the low supply current by

CMOS, the operating temperature is -40°C to 105°C and the maximum input voltage is 24V, the R1515x series are very suitable for

power source of car accessories.

ADOPTION OF DMOS PROCESS

R1150H

R1154x

R1500x

The DMOS (Double Diffused MOS) transistor adopted by

R1500x 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 R1500x 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.

from -40°C to 105°C that makes it suitable for use in

automotive and industrial applications involving higher

temperatures.

Thermal Shutdown Circuit

The Thermal Shutdown Circuit shown in the block diagram detects an increase in temperature, stops operation, and protects the regulator from

being damaged by a short circuit in the output pin (V^OUT) and ground pin (GND).

The Thermal Shutdown Circuit stops operation of the regulator when the junction temperature of the regulator exceeds 160°C. Moreover, when the junction

temperature decreases to a level below 135°C after the regulator has stopped, the regulator resumes to normal operation.

As a result, the operation of the Thermal Shutdown Circuit causes the regulator repeatedly to turn OFF and ON till the causes of overheating are

removed. As a consequence, a pulse shaped output voltage occurs. Care should be taken to prevent this situation.

In the datasheet it is shown as a thermal shutdown detection temperature (T^TSD) and a thermal shutdown release temperature (TTSR).
