Overview
The NCP699SN30T1G is a fixed output Low Dropout (LDO) linear voltage regulator from onsemi, designed specifically for handheld communication equipment and portable battery-powered applications. This device is part of the NCP699 series, which is characterized by its ultra-low quiescent current of 40 μA, making it highly suitable for power-efficient designs. The NCP699SN30T1G features a voltage reference unit, an error amplifier, a PMOS power transistor, and internal resistors for setting the output voltage, along with current limit and temperature limit protection circuits. It is housed in a micro-miniature TSOP-5 surface mount package and supports an output voltage of 3.0 V.
