1 / 20 page General Description The MAX6469–MAX6484 are low-dropout linear regula- tors 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 volt- age, and integrated reset functionality make these devices ideal for battery-powered portable equipment. The MAX6469–MAX6484 include a reset output that indi- cates 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 applica- tions. The MAX6469–MAX6476 are available in 6-pin SOT23 and 8-pin thin QFN 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.

Desired output voltages are set by the suffix found in the Output Voltage Suffix Guide (Table 1). The third “_” is a placeholder for the reset threshold accuracy. Desired reset threshold accuracy is set by the suffix found in the Reset Threshold Accuracy Guide (Table 2). The “_” following the D is a placeholder for the reset timeout delay time. Desired reset timeout delay time is set by the suffix found in the Reset Timeout Delay Guide (Table 3). For example, the MAX6481BL30BD4-T has a 3.0V output voltage, 12.5% reset threshold tolerance, and a 1200ms (min) reset timeout delay. Sample stock is generally avail- able on standard versions only (Table 4). Standard versions require a minimum order increment of 2.5k units. Nonstandard versions must be ordered in 10k-unit increments. Contact factory for availability. Ordering Information continued at end of data sheet. Pin Configurations appear at end of data sheet.
