IRU1246

The IRU1246/47 family of voltage regulators contain two integrated, low dropout linear voltage regulators in three different packages, such as new 5-Pin Ultra Thin-Pak surface mount, 5-Pin D-Pak and 8-Pin SOIC. The IRU1246 provides 3.3V fixed and adjustable outputs. The IRU1247-18 provides fixed 3.3V and 1.8V. The IRU1247- 25 provides fixed 3.3V and 2.5V output. These products are stable with both Ceramic and Tantalum output capacitors.

The adjustable output provides a voltage from 1.25V and up using a simple resistor divider. The input supply for both regulators is supplied from a single 5V supply. Each regulator is capable of 2 amps continuous load current. Both outputs, for each device, are current limit protected as well as having a thermal shutdown that protects the device from excessive temperature.
