The Texas Instruments LP3990MF-2.8 is a 150mA linear voltage regulator designed for digital applications. It provides a stable 2.8V output voltage from an input range of 2.0V to 6.0V.
Key electrical specifications include a low quiescent current of 43µA when enabled and less than 10nA in shutdown mode, making it suitable for battery-powered devices. The regulator offers a low dropout voltage of 0.2V at 150mA and features thermal-overload and short-circuit protection.
Designed for stability with ceramic capacitors as small as 1.0µF, it also boasts low output noise (150µVRMS) and a PSRR of 55dB at 1kHz. The device includes a logic-controlled enable pin for power management.
Packaged in a compact SOT-23-5 surface-mount package, the LP3990MF-2.8 is ideal for space-constrained applications requiring a reliable and efficient voltage regulation solution.
