What the LP5907 does
The LP5907 is a 250mA, low-noise, low-Iq LDO regulator available in commercial, industrial, and military temperature grades. It supports input voltages from 2.2V to 5.5V and output voltages from 1.2V to 4.5V. Key specifications include 82dB PSRR at 1kHz, 120mV typical dropout, and 12μA quiescent current. The device requires only 1µF ceramic capacitors for stability without a noise bypass component. It serves RF and analog circuits in smartphones, tablets, communications equipment, digital cameras, and factory automation. The part offers thermal overload and short-circuit protection across a junction temperature range of –40°C to 125°C.
