LDO regulator delivers 1.5A from voltages as low as 1.4V
The introduction of the XR71211 signals an expansion of Exar's existing range of LDO regulators. Targeted at 1.5V to 1.2V and 1.8V to 1.5V conversions, the device delivers 1.5A from voltages as low as 1.4V and has a guaranteed dropout voltage of 250mV at maximum junction temperature. The regulator is targeted at a wide range of markets including communications, enterprise solutions, industrial systems and space constrained consumer devices.
Exar achieves the low dropout performance of the XR71211 regulator without requiring either an external bias voltage or an internal charge pump, which can often generate unwanted noise and affect system operation. The new LDO uses a single supply which reduces board layout complexity by avoiding the need to route a secondary bias rail to the LDO. Operating input voltage range is 1.4V to 2.625V and the device provides output voltages down to 0.6V with an accuracy of 0.5% using ceramic capacitors. In addition, precision enable and power good functions allow for easy sequencing and control.
“The XR71211 builds on the industry leading technology developed for the XRP6274 and XRP6275,” said James Lougheed, vice president, power management, Exar. “Leveraging that technology, this latest addition to our high current LDO family is optimized for popular rail conversions such as 1.8V to 1.5V and 1.5V to 1.2V.”
The XR71211 is available now in RoHS compliant, green/halogen free space-saving 10-pin 3x3mm DFN package and is priced from $1.59 in 1000 piece quantities.
