R1171x SERIES

2.0A/1.5A LDO REGULATOR

OUTLINE

NO. EA-125-090202

The R1171x Series are CMOS-based positive voltage regulator ICs. The R1171x Series have features of 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 shutdown circuit. The output voltage of R1171 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 prolongs the battery life. These regulators are remarkable

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

Thus, the R1171x Series are suitable for various power sources.

Since the packages for these ICs are high wattage HSOP-6J package, TO-252-5-P1, high density mounting of

the ICs on boards is possible.
