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.

Notes
1) Applies over full temperature range :–
TJ = –55 to +150°C for IP1R07A / IP1R07
TJ =
0 to +125°C for IP3R07A / IP3R07
All other specifications apply at TJ = 25°C unless otherwise stated.
2) Test conditions unless otherwise stated :–
VC - VO = 5V , VP - VO = 3V , IOUT = 3A.
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.
