Micrel Rolls Out New High Speed, Dual Supply NMOS LDO for Low Input and Output Voltage Applications
SAN JOSE, California, April 2 --
Micrel Inc., (Nasdaq: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched the MIC47100, an 1A High Speed, NMOS LDO designed to take advantage of applications that that utilize multiple supply rails to generate a low voltage, high current power supply. The device is targeted at point-of-load, PDAs, DSPs, PLDs, FPGAs and low voltage post regulation applications. It is currently available in volume quantities and are priced at US$1.57 for 1K quantities in the MLF(R) package and US$1.62 for 1K quantities in the ePad SOIC-8 package.
"With its flexible design for output currents up to 1A, the MIC47100 is the market's best solution for low input and output voltage applications," noted Andy Cowell, Micrel's vice president of marketing for power products. "In addition, the device has fast transient response which makes it ideal for the market's most demanding bandwidth applications. With the high speed load, coupled with low Q current and low dropout voltage, the MIC47100 is idea for core voltages of mobile processors, post regulating a core DC-to-DC converter in any portable device."
The NMOS output stage of the MIC47100 makes for a unique ability to respond very quickly to sudden load changes such as that required by a microprocessor, DSP or FPGA. It can source 1A of programmable output current while only requiring a 1uF ceramic output capacitor for stability. The device offers an operating voltage range of 1.0V to 3.6V input supply, 2.3V to 5.5V bias supply and 200mV dropout. It comes with a 0.8V to 1.2V output voltage range and a PSRR of >50dB at 100kHz. The solution features a low dropout voltage of 80mV at 1A. It also gives designers high output voltage accuracy of +/- 1.5 percent initial accuracy and +/- 2 percent over temperature. The MIC47100 in an exposed pad MSOP-8 package or a tiny 2mm x 2mm MLF(R) package; the small form package being ideal for customers with limited board space.
The IC features a with an operating junction temperature range of -40-deg C to 125-deg C.
