The MIC49500-0.9WR from Microchip Technology is a high-current low dropout linear regulator providing a fixed 0.9V output at up to 5A. With a dropout voltage of just 0.5V at full load, it efficiently regulates from low-voltage input rails. The 7-SPAK package offers superior thermal dissipation, making it suitable for demanding applications like FPGA cores, DSPs, and server power supplies. Its 90mA quiescent current balances performance with efficiency for high-current designs.
- High Current Capacity: 5A output supports power-hungry digital loads.
- Ultra-Low Dropout: 0.5V at 5A maximizes efficiency in low-headroom designs.
- Low Input Operation: Works from 0.9V input, enabling single-cell battery use.
- Excellent Thermal Management: 7-SPAK package dissipates heat effectively for reliable operation.
FPGA Core Power Supplies
Modern FPGAs require low-voltage, high-current rails (0.9V at 5A). The MIC49500-0.9WR delivers this with a low 0.5V dropout, ensuring stable operation from a 1.4V source.
DSP and ASIC Power
Digital signal processors and custom ASICs often need 0.9V cores. This LDO provides clean, regulated power with minimal noise, critical for high-speed processing.
Server Motherboard VRMs
In server applications, the 7-SPAK package and 5A capability make it ideal for powering memory and logic circuits from intermediate bus voltages.
Telecom Line Cards
For networking equipment, the low dropout allows efficient conversion from 1.5V rails to 0.9V, reducing heat generation in dense boards.
Battery-Powered Handheld Devices
With a 0.9V input capability, it can operate directly from a single-cell battery, providing a regulated 0.9V output for low-power microcontrollers.
Automotive ECUs
Engine control units require reliable low-voltage supplies for sensors and microcontrollers; this LDO ensures stable 0.9V even under cranking conditions.
