LX8415-25

The LX8415 series ICs are positive Low Dropout (LDO) regulators. At the designed maximum load current, the LX8415 series dropout voltage is guaranteed to be 1.3V or lower at 0.5A. The dropout voltage decreases with load current.

The LX8415 is available in an adjustable output voltage version and fixed output versions of 2.5V and 3.3V. Onchip trimming of the internal voltage reference allows specification of the initial output voltage to within ±1% of its nominal value. The output currentlimit point is also trimmed, which helps to minimize stress on both the regulator and the system power source when they are operated under short-circuit conditions. The regulator's internal circuitry will operate at input-to-output differential voltages down to 1V.

Most regulator circuit designs include output capacitors with values in the range of tens to hundreds of microfarads or more. The LX8415 typically requires at least 10F of output capacitance for stable operation.

The LX8415 is available in the lowprofile plastic SOT-223 package for applications where space is at a premium.
