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.

Although Power Dissipation is internally limited, these specifications apply for Power Dissipation up to 50W. 3) Load and Line regulation are electrically independent and are measured using pulse techniques at low duty cycle in order to maintain constant junction temperature. To determine the effects on the output voltage due to device heating, refer to thermal regulation specification.
