MIC5319
500mA µCap Ultra-Low Dropout
High PSRR LDO Regulator
General Description
The MIC5319 is a high-performance, 500mA LDO
regulator, offering extremely high PSRR and very-low
noise while consuming low ground current.
Ideal for battery-operated applications, the MIC5319
features 1% accuracy, extremely low-dropout voltage
(200mV @ 500mA), and low ground current at light load
(typically 90µA). Equipped with a logic-compatible enable
pin, the MIC5319 can be put into a zero-off-mode current
state, drawing no current when disabled.
The MIC5319 is a µCap design operating with very-small
ceramic output capacitors for stability, thereby reducing
required board space and component cost.
The MIC5319 is available in fixed-output voltages and
adjustable output voltages in the super-compact 2mm x
2mm MLF
®
leadless package and thin SOT-23-5 package.

Please tell me the relationship between the P4CPU 32-bit address bus and 64-bit data bus, and how they work.
As the title says. Also: Is access usually done through the address bus or the data bus? P4 has a 64-bit data bus, so why can 32-bit Windows only access 32 bits?...
