LOW NOISE 150mA LDO REGULATOR
R1113Z SERIES
s
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 transient
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.
