Description & ApplicationsHIGH 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
描述与应用高纹波抑制率低压差 高输出电流CMOS电压稳压器;•输出电压:1.0 V至5.0 V,V可选步骤在0时05分。 •低等效串联电阻电容:4.7μF以上的陶瓷电容器可作为    I / O电容器。 •输入电压:1.5 V至5.5 V •高输出电压精度:±1.0%(1:45 V至1.0 V输出产品:±15毫伏) •低压差电压:70 mV典型。 (3.0 V输出产品,IOUT= 300 mA时) •低电流消耗:在操作过程中:70μA(典型值),最大90μA。    (3.0 V输出产品) 休眠时:0.1μA(典型值),1.0μA最大值。 •输出电流:1000毫安(3.0 V输出产品,VIN≥VOUT(S)+1.0 V) •高纹波抑制:70 dB(典型值)。 (1.0千赫,VOUT= 1.0 V) •内置过电流保护电路:限制输出晶体管的过载电流 •内置热关断电路:预防造成的损失。 •内置突入电流控制电路限制启动期间的浪涌电流过大 •内置电源开/关控制电路的电池寿命更长
