save power.
This section explains how to generate a 1.5-V supply from another system
supply. Supplying power to the 1.5-V logic array and/or I/O pins
requires a 5.0-V- or 3.3-V-to-1.5-V voltage regulator. A linear regulator is
ideal for low-power applications because it minimizes device count and
has acceptable efficiency for most applications. A switching voltage
regulator provides optimal efficiency. Switching regulators are ideal for
high-power applications because of their high efficiency.
This section will help you decide which regulator to use in your system,
and how to implement the regulator in your design. There are several
companies that provide voltage regulators for low-voltage devices, such
as Linear Technology Corporation, Maxim Integrated Products, Intersil
Corporation (Elantec), and National Semiconductor Corporation.
