The Texas Instruments LP3990TLX-0.8/NOPB is a 150mA linear voltage regulator offering a fixed 0.8V output. Designed for portable and battery-powered systems, it provides stable operation with ceramic capacitors as low as 1µF. Key features include a logic-controlled enable pin for low power consumption in shutdown mode and thermal-overload and short-circuit protection.
This regulator operates from an input voltage range of 2V to 6V and delivers a 1% voltage accuracy at room temperature. It boasts low output noise of 150µVRMS and a PSRR of 55dB at 1kHz, making it suitable for noise-sensitive digital applications. The device is available in a compact 4-DSBGA package, ideal for space-constrained designs.
With a fast start-up time of 105µs and very low quiescent current when enabled (43µA), the LP3990 is an efficient choice for power management in handheld devices and information appliances. Its robust protection features ensure reliable operation under various conditions.
