XRP6272 Datasheet | MaxLinear

DESCRIPTION The XRP6272 is a low dropout voltage regulator capable of a constant output current up to 2 Amps. A wide 1.8V to 6V input voltage range allows for single supply operations from industry standard 1.8V, 2.8V, 3.3V, and 5V power rails as well as the 5.8V rail. With better than ±2% output voltage accuracy, low output noise and high Power Supply Rejection Ratio (PSRR), the XRP6272 is perfectly suited for powering RF circuitries. Optimized for use with small low cost ESR ceramic output capacitors and featuring a low 30µA quiescent current, this device is also adequate for use in battery powered portable equipments. The XRP6272 operates by default as a 5V fixed output voltage regulator while usage of an external resistors divider allows adjustable out voltages as low as 0.7V. An Enable function, Power Good flag and output noise reduction pin plete the feature set. Built-in current limit and thermal protections insure safe operations under abnormal operating conditions. The XRP6272 is offered in Ro HS pliant, “green”/halogen free 5-pin TO-252 and 8-pin exposed pad SOIC packages.
