onsemi NCP187 / NCV8187 VREG

The NCP187 is a 1.2 A Low Dropout Linear Voltage Regulator (LDO). It is a very stable and accurate device with low quiescent current consumption (typically 30 A over the full temperature range). It features low dropout, low output noise, and a very good Power Supply Rejection Ratio (PSRR)

The regulator incorporates several protection features such as Thermal Shutdown, Soft Start, Current Limiting, and also Power Good Output signal for easy MCU interfacing. There is also an automotive-grade version with the NCV prefix (NCV8187) that is AEC-Q100 qualified and PPAP capable.
