Texas Instruments Voltage Regulators - Linear LP3986BL-2929

The LP3986BL-2929 is a dual low-dropout voltage regulator designed for portable and wireless applications, providing a maximum output current of 150 mA per regulator. It operates with a typical dropout voltage of 60 mV at full load, ensuring efficient power management. The device features a fast turn-on time of 200 µs and is stable with a small 1 µF ceramic output capacitor, making it suitable for space-constrained designs. This regulator includes logic-controlled enable inputs for both outputs, as well as built-in overcurrent and thermal protection, enhancing reliability in various applications. The LP3986 is optimized for battery-powered systems, offering low quiescent current of 115 µA and output noise of 40 µV, which contributes to extended battery life. It operates over a temperature range of -40°C to +125°C and is packaged in a miniature 8-I/O DSBGA format, facilitating integration into compact electronic devices.
