LDO选型和DC/DC选型

1.  input voltage 3.3V  output voltage 2.5V   output current 0.16A MAX   pls help to select LDO?

2.  input voltage 5V  output voltage 1V   output current 16A MAX   pls help to select DC/DC?

3.   input voltage 5V  output voltage 1V   output current 6A MAX   pls help to select LDO?

Bryant,

   What's your application and product? do you have some other requirememts? For instance, BOM cost, size, effiency and so on?

Here are some recommendation:

1. LDO: TLV70025 or TLV70525

2. DC/DC : TPS53353 or TPS56221 or LM2743

3. LDO: 5 Vin 1Vout @6A, we do not recommend u to use LDO, because of power consumption 24W. Please use DC/DC : TPS54620 or TPS54618
