RP6272 XXRP6272 2A 5V-Adjustable Low Dropout Voltage Regulato 2A 5V-Adjustable Low Dropout Voltage Regulatorr September 10, 2021 Rev. 1.2.2 GENERAL DESCRIPTION APPLICATIONS The XRP6272 is a low dropout voltage Networking Equipments regulator capable of a constant output current RF Circuitry Power Supplies up to 2 Amps. A wide 1.8V to 6V input voltage range allows for single supply operations from Set-top box Equipments industry standard 1.8V, 2.8V, 3.3V, and 5V Portable Equipments power rails as well as the 5.8V rail. With better than 2% output voltage FEATURES accuracy, low output noise and high Power Supply Rejection Ratio (PSRR), the XRP6272 is Guaranteed 2A Output Current perfectly suited for powering RF circuitries. Low 550mV Dropout at 3.3V/2A Optimized for use with small low cost ESR 1.8V to 6V Single Input Voltage Range ceramic output capacitors and featuring a low 30A quiescent current, this device is also Fixed 5V and Adjustable Output Voltage adequate for use in battery powered port able 2% Output Voltage Accuracy equipments. The XRP6272 operates by default 30A Quiescent Current as a 5V fixed output voltage regulator while usage of an external resistors divider allows Power Good and Enable Functions adjustable out voltages as low as 0.7V. An 70dB Power Supply Rejection Ratio Enable function, Power Good flag and out put noise reduction pin complete the feature set. Low Output Noise Built-in current limit and thermal protections 0.01A Shutdown Current insure safe operations under abnormal Current Limit and Thermal Protection operating conditions. RoHS compliant Green/Halogen Free The XRP6272 is offered in RoHS compliant, 5-pin TO-252 and 8-pin Exposed pad green/halogen free 5-pin TO-252 and 8-pin SOIC Packages exposed pad SOIC packages.
