LOW NOISE 150mA LDO REGULATOR

R1113Z SERIES

NO. EA-101-0504

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.
