Description
The IP3R07A series of low dropout adjustable voltage
regulators are capable of supplying 3A of output current
with an input-to-output voltage of just 0.8V. In applications
where high efficiency is necessary it is now possible to
obtain a low cost, single chip solution. These regulators
are exceptionally easy to use, requiring only two external
resistors to set the output voltage.
The IP3R07A exhibits an initial ±1% output voltage
tolerance, and over all operating conditions the reference
voltage is guaranteed not to vary more than ±2%. These
devices include internal current limiting, thermal overload
protection, and power device safe operating area
compensation.
