＊R5324D (SON-8) is the discontinued product. As of March in 2015.

R5324x SERIES

TRIPLE LDO

OUTLINE

NO. EA-099-140530

The R5324x Series are CMOS-based multi positive voltage regulator ICs with high output voltage accuracy,

low supply current, low noise, low dropout and high ripple rejection. The R5324x Series contain three voltage

regulators. Each of these voltage regulators in the R5324x Series consists of a voltage reference unit, an error

amplifier, resistors for setting output voltage, a short current limit circuit, a chip enable circuit, and so on.

The chip enable function contributes to prolong battery life. Further, regulators in the R5324x Series are with

low dropout voltage, excellent load transient response and line transient response, thus the R5324x series are

very suitable for the power supply for hand-held communication equipment.

Since the packages for these ICs are SON-8 and DFN(PLP)2527-10, high density mounting of the ICs on

boards is possible.
