R1113Z SERIES
Non-promotion
LOW NOISE 150mA LDO REGULATOR
NO.EA-101-120404
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-CSP4-P1
(Wafer Level CSP), high density mounting of the ICs on boards is possible.
