PRELIMINARY

LOW NOISE 150mA LDO REGULATOR

R1113Z SERIES

■ 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.

Excellent Dynamic Response

Small Package ..........................................................WL-CSP(Wafer Level CSP)

Output Voltage...........................................................Stepwise setting with a step of 0.1V in the range of 2.0V to 5.0V is

possible

Built-in Chip Enable Circuit ( 2 types; A: active low , B: active high)

Built-in Fold Back Protection Circuit........................Typ. 30mA (Current at short mode)

Ceramic capacitors are recommended to be used with this IC

■ APPLICATIONS

Power source for cellular phones such as GSM, CDMA and various kinds of PCS.

Power source for electrical appliances such as cameras, VCRs and camcorders.

Power source for battery-powered equipment.
