Description

The MAX8940 low-noise, low-dropout (LDO) linear regulator is designed to deliver up to 120mA continuous output current. This regulator achieves a low 120mV dropout for 120mA load current. The MAX8940 uses an advanced architecture to achieve low output voltage noise of 25µVRMSand PSRR of 45dB at 100kHz.The MAX8940 is preset to either 2.8V or 3.0V. Designed with a p-channel MOSFET series pass transistor, the MAX8940 maintain very low ground current (40µA).The regulator is designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8940 requires only 1µF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1µA.Package is a 5-pin SC70.ApplicationsBase StationsBluetooth Portable Radios and AccessoriesCellular and Cordless PhonesDigital CamerasPDA and Palmtop ComputersPersonal StereosPortable and Battery-Powered EquipmentWireless LANs
