LP3990MF-1.8/NOPB Description

Short technical summary and product information.

The Texas Instruments LP3990MF-1.8/NOPB is a low-dropout (LDO) linear voltage regulator designed for portable and battery-powered systems. It provides a stable 1.8V output voltage with a maximum load current of 150mA, drawing a typical quiescent current of 43µA when enabled.

 

Key electrical specifications include an input voltage range of 2V to 6V and a low dropout voltage of 0.2V at 150mA. The regulator features thermal-overload and short-circuit protection, along with a logic-controlled enable pin for power management. It is designed to be stable with ceramic capacitors as low as 1µF and offers low output noise of 150µVRMS.

 

This device is supplied in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package, making it suitable for space-constrained applications. The operating temperature range is -40°C to 85°C.

 

Applications for this regulator include cellular handsets and hand-held information appliances where low power consumption and stable voltage regulation are critical.
