Description

General part information

MAX8840 Series

The MAX8840/MAX8841/MAX8842 ultra-low-noise, low-dropout (LDO) linear regulators are designed to deliver up to 150mA continuous output current. These regulators achieve a low 120mV dropout for 120mA load current. The MAX8840 uses an advanced architecture to achieve ultra-low output voltage noise of 11µVRMSand PSRR of 54dB at 100kHz.The MAX8841 does not require a bypass capacitor, hence achieving the smallest PC board area. The MAX8842 output voltage can be adjusted with an external divider.The MAX8840/MAX8841 are preset to a variety of voltages in the 1.5V to 4.5V range. Designed with a p-channel MOSFET series pass transistor, the MAX8840/MAX8841/MAX8842 maintain very low ground current (40µA).The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8840 requires only 1µF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1µA.The MAX8840/MAX8841/MAX8842 are available in a tiny 1mm x 1.5mm x 0.8mm µDFN.ApplicationsBase StationsBluetooth® Portable Radios and AccessoriesCellular and Cordless PhonesDigital CamerasPDA and Palmtop ComputersPersonal StereosPortable and Battery-Powered EquipmentWireless LANs
