The LX8415 series ICs are positive Low

Dropout (LDO) regulators. At the de-

signed maximum load current, the

LX8415 series dropout voltage is guar-

anteed to be 1.3V or lower at 0.5A. The

dropout voltage decreases with load

current.

able output voltage version and fixed

output versions of 2.5V and 3.3V. On-

chip trimming of the internal voltage

reference allows specification of the

initial output voltage to within ±1% of

its nominal value. The output current-

limit point is also trimmed, which helps
