【经验】解析SGMICRO线性稳压器SGM2049的设计注意事项
SGMICRO推出的SGM2049是一款低噪声、超低压降的线性稳压器,输入电压低至1.1V。它能够提供2A的输出电流,典型的压降电压只有70mV。SGM2049的输出电压可从电压配置引脚进行单独选择或者组合使用(0.8V~3.95V),如不能组合出所需要的电压,还可以用外部电阻从0.8V到5.2V进行调节。
SGM2049具有软启动、PG(POWER GOOD)功能,其高精度、低噪声、高PSRR和高输出电流能力,非常适合为模数转换器(ADC)、数模转换器(DAC)和射频组件等噪声敏感设备供电。
SGM2049有绿色TQFN-3.5×3.5-20L和TQFN-5×5-20L封装,工作温度范围为:-40℃至+125℃,如下为其封装图:
如下为一些设计注意事项,避免SGM2049不能正常工作:
1、 SNS引脚为电压输出方式配置脚,如使用电压配置引脚输出电压,SNS需连接到OUT脚;如使用外部电阻调节输出电压,则SNS不接,悬空处理;
2、 输入电压大于1.4V时,BIAS引脚有多种处理方式,接偏压、悬空或者接地都可以;
3、 输入电压小于1.4V时,如Vin=1.2V,Vout=1V,BIAS引脚必须加偏压。
