MIC47100 Datasheet | Micrel Semiconductor

Description Features - Operating voltage range: - Input Supply: 1.0V to 3.6V - Bias Supply: 2.3V to 5.5V - 0.8V to 2.0V output voltage range - High bandwidth - very fast transient response - PSRR >50d B at 100k Hz - Stable with a 1µF ceramic output capacitor - Low dropout voltage of 80m V at 1A - High output voltage accuracy: - +/- 1.5% initial accuracy - +/- 2% over temperature - Logic level enable input - UVLO on both supply voltages for easy turn-on - e Pad MSOP-8 - small form factor power package - Thermally enhanced 2mm × 2mm MLF® - smallest solution The MIC47100 is a high speed, Low VIN LDO capable of delivering up to 1A and designed to take advantage of point of load applications that use multiple supply rails to generate a low voltage, high current power supply. The MIC47100 is stable with only a 1µF ceramic output capacitor and is available in a thermally enhanced 2mm × 2mm MLF® package thus making it an optimal solution for board-constrained applications. The MIC47100 has an NMOS output stage offering very low output impedance. The NMOS output stage offers a unique ability to respond very quickly to sudden load changes such as that required by a microprocessor, DSP or FPGA. The MIC47100 consumes little quiescent current and therefore can be used for driving the core voltages of mobile processors, post regulating a core DC/DC converter in any portable device. The MIC47100 is available in fixed and adjustable output voltages in the exposed pad MSOP-8 package and the tiny 2mm × 2mm MLF® package with an operating junction temperature range of -40°C to +125°C.
