4.5-5.5V 1ch Nch FET LDO Controllers - BD3521FVM
This IC is an ultra-low dropout linear regulator controller for chipset that can achieve ultra-low voltage input to ultra-low voltage output. By using N-MOSFET for external power transistor, the controller can be used at ultra-low I / O voltage difference up to voltage difference generated by ON resistance. In addition, because best suited power transistor can be chosen in accord with the output current, downsizing and cost reduction of the set can be achieved. Because by reducing the I / O voltage difference, large current output is achieved and conversion loss can be reduced, switching power supply can be replaced. This IC does not need any choke coil, diode for rectification and power transistor which are required for switching power supply, total cost of the set can be reduced and compact size can be achieved for the set. In addition, since voltage output start-up time can be adjusted by using the NRCS terminal, it is possible to flexibly meet the power supply sequence of the set.
