Applications Information The MIC49500 is an ultra-high performance, low dropout linear regulator designed for high current applications requiring fast transient response. The MIC49500 utilizes two input supplies, significantly reducing dropout voltage, perfect for low-voltage, DC- to-DC conversion. The MIC49500 requires ...
Page 9
The low dropout properties of the MIC49500 allow significant reductions dissipation and the associated heat sink without compromising performance. When this technique is employed, a capacitor of at least 1µF is needed directly between the input and regulator ground. ...
