R1170H Series

800mA LDO Regulator for Automotive Applications

NO.EC-084-131206

OUTLINE

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, and 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.

This device is packaged in SOT-89-5 that achieves high-density mounting on boards.
