NO. EA-101-0301
OUTLINE
The R1113Z Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low supply
current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error
amplifier, resistors, a current limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function. The line transient response and load tran-
sient response of the R1113Z Series are excellent, thus these ICs are very suitable for the power supply for hand-held
communication equipment.
The output voltage of these ICs is fixed with high accuracy. Since the package for these ICs is WL-CSP (Wafer
Level CSP), high density mounting of the ICs on boards is possible.

In these ICs, fluctuation of output voltage, V
OUT
is detected by feedback registers R1, R2, and the result is com-
pared with a reference voltage by the error amplifier, so that a constant voltage is output. A current limit circuit for
protection in short mode and a chip enable circuit, are included.
