Description

General part information

MAX6473 Series

The MAX6469–MAX6484 are low-dropout linear regulators with a fully integrated microprocessor reset circuit. Each is available with preset output voltages from +1.5V to +3.3V in 100mV increments and delivers up to 300mA of load current. These devices consume only 82µA of supply current. The low supply current, low dropout voltage, and integrated reset functionality make these devices ideal for battery-powered portable equipment.The MAX6469–MAX6484 include a reset output that indicates when the regulator output drops below standard microprocessor supply tolerances (-7.5% or -12.5% of nominal output voltage). This eliminates the need for an external microprocessor supervisor, while ensuring that supply voltages and clock oscillators have stabilized before processor activity is enabled. Push-pull and open-drain active-low reset outputs are available, with reset timeout periods of 2.5ms, 20ms, 150ms, or 1200ms (min).The MAX6469/MAX6470/MAX6473–MAX6478/MAX6481–MAX6484 also have a shutdown feature that reduces the supply current to 0.1µA (typ). The MAX6471-MAX6474/MAX6479–MAX6482 offer a manual reset input to assert a microprocessor reset while the regulator output is within specification. The MAX6475/MAX6476/MAX6483/MAX6484 feature a remote feedback sense pin for use with an external NPN transistor for higher-current applications. The MAX6469–MAX6476 are available in 6-pin SOT23 and 8-pin TDFN packages. The MAX6477–MAX6484 are available in a 3 × 3 chip-scale package (UCSP™). All devices are specified for operation from -40°C to +85°C.ApplicationsBluetooth® Modules/Wireless LANCD/DVD DrivesCell Phones/Cordless PhonesDigital CamerasHandheld Instruments (PDAs, Palmtops)Notebook ComputersPCMCIA Cards/USB Devices
