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.
