1 / 18 page LOW NOISE 150mA LDO REGULATOR R1113Z SERIES NO. EA-101-0504 1 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. FEATURES • Ultra-Low Supply Current................................................Typ. 100µA • Standby Mode .................................................................Typ. 0.1µA • 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-CSP4-P1 (Wafer Level CSP) • Output Voltage .................................................. .............Stepwise setting with a step of 0.1V in the range of 1.5V to5.0V 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. |
