Exar releases world's lowest voltage single supply LDOs with 140 mV dropout

Exar XRP6274 XRP6275

Exar Corporation announced two ground breaking low-dropout (LDO) regulators that support 2 A and 3 A loads from a single low voltage supply with a maximum dropout voltage of 140 mV. The XRP6274  and XRP6275 ultra low dropout voltage regulators can operate with industry standard low voltage rails of 1.1 V to 2.5 V providing a unique single supply solution for convenient point-of-load voltage regulation. The new LDOs are targeted at a wide range of markets including communications, enterprise solutions, industrial systems and space constrained consumer devices.

Exar - XRP6274, XRP6275

Exar achieves the ultra low dropout performance of its XRP6274 and XRP6275 regulators without requiring either an external bias voltage or an internal charge pump, which can often generate unwanted noise and affect system operation. The new ultra LDO's use a single supply and reduce board layout complexity by avoiding the need to route a secondary bias rail to the LDO. The start up is guaranteed from an input voltage as low as 1.045 V. The XRP6274/75 devices provide output voltages down to 0.6 V with an accuracy of 0.5% using ceramic capacitors. In addition, precision enable and power good functions allow for easy sequencing and control of these LDOs.
