MIC47050
500mA ULDO? with Low Input
and Low Output Voltage
General Description
The MIC47050 is a high-speed, ultra-low dropout, dual-
supply NMOS ULDO? designed to take advantage of
point-of-load applications that use multiple supply rails to
generate a low-voltage, high-current power supply. The
MIC47050 can source 500mA of output current while only
requiring a 1 μ F ceramic output capacitor for stability. A
1.5% output voltage accuracy, low dropout voltage (44mV
@ 500mA), and low ground current makes this device
ideally suited for mobile and point-of-load applications.
The MIC47050 has an NMOS output stage offering very
low output impedance. The NMOS output stage makes for
a unique ability to respond very quickly to sudden load
changes such as that required by a microprocessor, DSP
or FPGA. The MIC47050 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 processor.
The MIC47050 is available in fixed and adjustable output
voltages in the tiny 2mm x 2mm MLF ? and Thin MLF ?
packages with an operating junction temperature range of
? 40 ? C to ? 125 ? C.
