| Description & Applications | HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR ;•Output voltage : 1.0 V to 5.0 V, selectable in 0.05 V step. •Low equivalent series resistance capacitor : Ceramic capacitor of 4.7 μF or more can be used as the I/O capacitor. • Input voltage : 1.5 V to 5.5 V • High-accuracy output voltage : ±1.0% (1.0 V to 1.45 V output product : ±15 mV) • Low dropout voltage : 70 mV typ. (3.0 V output product, at IOUT = 300 mA) • Low current consumption : During operation : 70 μA typ., 90 μA max. (3.0 V output product) During shutdown : 0.1 μA typ., 1.0 μA max. • Output current : 1000 mA (3.0 V output product, at VIN ≥ VOUT(S) + 1.0 V) • High ripple rejection : 70 dB typ. (at 1.0 kHz, VOUT = 1.0 V) • Built-in overcurrent protection circuit : limits overcurrent of output transistor • Built-in thermal shutdown circuit : prevents damage caused by heat • Built-in rush current control circuit : limits excessive rush current during start-up • Built-in power on/off circuit : Longer battery life |
