R1170x SERIES

800mA LDO REGULATOR

OUTLINE

NO.EA-084-0607

The R1170x Series are positive voltage regulator ICs by CMOS process. The R1170x Series have features of

high ripple rejection, low dropout voltage, high output voltage accuracy, low consumption current. Each of these

ICs consists of a voltage reference unit, an error amplifier, resistor net for setting output voltage, a current limit

circuit at short mode, a chip enable circuit, and thermal-shunt circuit. Output Voltage of R1170 is fixed in the IC.

Low consumption current by the merit of CMOS process and built-in transistors with low ON-resistance make

low dropout voltage and chip enable function prolong the battery life. These regulators are remarkable

improvement on the current regulators in terms of ripple rejection, input transient response, and load transient

response.

Maximum Output Current is large for its compact size.

Thus, the R1170x Series are suitable for various power sources for portable appliances.

Since the packages for these ICs are the SOT-89-5 package, HSON-6,or HSOP-6J, high density mounting of

the ICs on boards is possible.
