4 Note 1: For the adjustable device, the minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor divider used to set the output voltage is selected to meet the minimum load current equirement. Note 2: These parameters, although guaranteed, are not tested in production. SOT-223 封装外形尺寸(SOT-223 DIMENSION) VIN VOUT A/G *2005 年第
