AMS1117手册中的Minimum Load Current具体是什么意思啊?
手册里说的是The minimum output current required to maintain regulation.难道应用时一定要大于这个电流吗?有10mA之多啊.
手册里说的是The minimum output current required to maintain regulation.难道应用时一定要大于这个电流吗?有10mA之多啊.
先补充完整:
Note 5: Minimum load current is defined as the minimum output current required to maintain regulation. When 1.5V ≤ (VIN - VOUT) ≤ 12V the device is
guaranteed to regulate if the output current is greater than 10mA.
是说保证满足特性表中所列示的负载调整指标时, 输出电流的最小值.而表前明确标明：
Electrical Characteristics at IOUT = 0 mA, and TJ = +25°C unless otherwise specified.
就是说,输出电流可以为 0 mA.只是在IOUT
