MAX8860

19-1422; Rev 1; 12/99 Low-Dropout, 300mA Linear Regulator in µMAX General Description The MAX8860 low-noise, low-dropout linear regulator operates from a +2.5V to +6.5V input and is guaranteed to deliver 300mA. Typical output noise for this device is 60µVRMS, and typical dropout is 105mV at 200mA. In addition to the six available preset output voltages (+1.8V, +2.5V, +2.77V, +2.82V, +3.0V, and +3.3V), the Dual Mode™ feature allows the device to be configured as an adjustable output regulator from +1.25V to +6.5V. Designed with an internal P-channel MOSFET pass transistor, the MAX8860 has a low 120µA supply current. An output fault-detection circuit indicates loss of regulation. Other features include a 10nA, logic-controlled shutdown mode, short-circuit and thermal-shutdown protection, and reverse battery protection. The MAX8860 is available in a miniature 8-pin µMAX package. o High Output Current (300mA) o Low Output Voltage Noise: 60µVRMS o Low 105mV Dropout at 200mA Output o Low 120µA No-Load Supply Current o Thermal-Overload and Short-Circuit Protection o Reverse Battery Protection o 10nA Logic-Controlled Shutdown o FAULT Indicator o Small, Space-Saving µMAX Package (1.1mm max height) o Small 2.2µF Output Capacitor Saves Space and Cost Features MAX8860 Applications Wireless Handsets DSP Core Power PCMCIA Cards Hand-Held Instruments Palmtop Computers Electronic Planners MAX8860EUA18 MAX8860EUA25 MAX8860EUA27 MAX8860EUA28 MAX8860EUA30 MAX8860EUA33 -40°C to +85°C -40°C t...
