1 / 20 page '2001.8.27 LOW NOISE 150mA LDO REGULATOR R1113Z SERIES Rev. 1.11 - 1 - 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. s FEATURES Ultra-Low Supply Current......................................... Typ. 100 µA Standby Mode ........................................................... Typ. 0.1 µA Low Dropout Voltage ................................................ Typ. 0.23V(IOUT=100mA 3.0V Output type) High Ripple Rejection ............................................... Typ. 80dB(f=1kHz 3.0V Output type) Low Temperature-Drift Coefficient of Output Voltage Typ. ±100ppm/ °C Excellent Line Regulation ......................................... Typ. 0.05%/V High Output Voltage Accuracy.................................. ±2.0% 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 s 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. |
