MIC5190

Ultra High-Speed, High-Current Active Filter/LDO Controller

Features

General Description

• Input voltage range:

The MIC5190 is an ultra high-speed linear regulator. It uses

an external N-Channel FET as its power device.

= 0.9V to 5.5V

• +1.0% initial output tolerance

• Dropout down to 25mV@10A

The MIC5190 offers ultra high-speed to cope with the fast

load demands of microprocessor cores, ASICs, and other

high-speeddevices.Signalbandwidthsofgreaterthan500kHz

can be achieved with a minimum amount of capacitance

while at the same time keeping the output voltage clean,

regardless of load demand. A powerful output driver delivers

large MOSFETs into their linear regions, achieving ultra-low

dropout voltage.

• Filters out switching frequency noise on input

• Very high large signal bandwidth >500kHz

• PSRR >40dB at 500kHz

• Adjustable output voltage down to 0.5V

• Stable with any output capacitor

• Excellent line and load regulation specifications

• Logic controlled shutdown

• Current limit protection

1.25V ±10% can be turned into 0.9V ±1% without the use of

a large amount of capacitance.

• 3mm × 3mm 10-lead MLF™ and MSOP-10 packages

• Available –40°C to +125°C junction temperature

MIC5190 (0.5V reference) is optimized for output voltages of

below 1.0V.

The MIC5190 is offered in 10-lead 3mm × 3mm MLF™ and

10-lead MSOP-10 packages and has an operating junction

temperature range of –40°C to +125°C.
