R1162x SERIES

3-MODE 150mA LDO REGULATOR

NO.EA-110-0512

OUTLINE

The R1162x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy and low

supply current. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier,

resistors for setting output voltage, a current limit circuit, and so on. The output voltage is internally fixed with

high accuracy.

These ICs perform with the chip enable function and realize a standby mode with ultra low supply current. To

prevent the destruction by over current, the current limit circuit is included. The R1162x Series have 3-mode.

One is standby mode with CE or standby control pin. Other two modes are realized with ECO pin™. Fast

Transient Mode (FT mode) and Low Power Mode (LP mode) are alternative with ECO pin™. Consumption

current is reduced at Low Power Mode compared with Fast Transient Mode. The output voltage is maintained

between FT mode and LP mode.

Since the packages for these ICs are SOT-23-5 and SON1612-6 packages, high density mounting of the ICs

on boards is possible.
