NCP3521DMR2G

Overview

The NCP3521DMR2G is a Low Drop Out (LDO) regulator controller designed for high-current applications requiring ultra-low dropout voltages. It features a fixed 1.5 V output voltage tolerance of 1%. The device utilizes an external NMOS driver to adapt to various system requirements. Key electrical characteristics include a sleep mode current of less than 10 µA, a run mode supply current of 1.7 mA, and a short circuit latch condition current of 1.7 mA. It operates within a junction temperature range of -10°C to 150°C.

Feature Summary

Fixed 1.5 V output voltage option with 1% tolerance
Low operating and standby currents including sleep mode below 10 µA
Non Rush Current on Startup (NRCS) prevents high inrush currents
Integrated short circuit protection with latching capability

Applications

Set-Top Boxes
Gaming Consoles
LCD Televisions
FPGA Power Supplies
Networking Equipment

Procurement Notes

Verify the specific ordering suffix DMR2G corresponds to the Micro8 package and tape & reel shipping configuration. Confirm that the component is lead-free as indicated by the datasheet designation. Ensure compatibility with the required external NFET selection for the target current application.

Selection Notes

Select this controller when a fixed 1.5 V output is required with high current capability defined by an external MOSFET. Consider the NRCS feature for managing startup inrush and the low standby current for power-sensitive systems. Validate the external FET choice against the VS pulldown specifications for optimal transient response.

Part Context

This component belongs to the NCP3520/NCP3521 family of LDO regulator controllers from onsemi. It serves as a drop-in replacement for Rohm BD3521FVM and is functionally equivalent to the BD3502FVM. The family allows designers to customize current handling via external components while maintaining precise voltage regulation.

Replacement Considerations

The NCP3521DMR2G is a direct drop-in replacement for the Rohm BD3521FVM. It is also functionally equivalent to the Rohm BD3502FVM. Verify pinout compatibility and external component values when substituting these parts.
