R1115Z SERIES

LOW NOISE 150mA WL-CSP LDO

OUTLINE

NO.EA-107-0512

The R1115Z Series are CMOS-based voltage regulator ICs with extremely low supply current, low

ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier,

resistor-net for voltage setting, 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 R1115Z 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 packages for these ICs is WL-CSP4-P4,

therefore high density mounting of the ICs on boards is possible.

• High Ripple Rejection .......................................................... Typ. 70dB (f=1kHz 3.0V Output type)

Typ. 60dB (f=10kHz)

• Low Temperature-Drift Coefficient of Output Voltage........... Typ. ±100ppm/°C

• Excellent Line Regulation .................................................... Typ. 0.02%/V

• High Output Voltage Accuracy ............................................. ±2.0%

•

Small Packages ................................................................. WL-CSP4-P4

• Output Voltage ..................................................................... Stepwise setting with a step of 0.1V in

the range of 1.5V to 4.0V is possible

• Built-in Fold Back Protection Circuit .................................... Typ. 40mA (Current at short mode)

•

Ceramic capacitors are recommended to be used with this IC ... CIN=COUT=1µF (VOUT<2.5V)

C^IN=1µF, COUT=0.47µF (VOUT 2.5V)

APPLICATIONS
