点击查看特定型号的库存状况。

说明

The MAX38902A/B/C/D are low-noise, linear regulators that deliver up to 500mA of output current with only 12μVRMS of output noise from 10Hz to 100kHz. These regulators maintain ±1% output accuracy over a wide input voltage range, requiring only 100mV of input-tooutput headroom at full load. The 365μA no-load supply current is independent of drop-out voltage.

The MAX38902A have nine, pin-selectable output voltages 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 4.0V, and 5V. The MAX38902B/C have a resistor adjustable output voltage in the range of 0.6V to 5.3V. The MAX38902B also includes an active-low POK output.

The MAX38902D have factory-preset output voltages ranging from 0.7V to 5V. All versions include a programmable output soft-start rate, output over-current and thermal overload protection.

The MAX38902A/B are offered in an 8-pin TDFN package, while the MAX38902C/D are offered in a 2 x 3, 0.4mm wafer-level package (WLP).
