Texas Instruments Voltage Regulators - Linear Regulator Controllers LP3986TL-2818

The LP3986TL-2818 is a dual low dropout (LDO) voltage regulator capable of delivering 150 mA output current per regulator. It is designed for portable and wireless applications, emphasizing low noise, low dropout voltage, and low quiescent current, which is particularly beneficial for battery-powered systems. The device operates with a small 1 ¬µF ceramic output capacitor, allowing for minimal board space usage. Key specifications include a typical dropout voltage of 60 mV at 150 mA output current, a quiescent current of 115 ¬µA, and an output noise of 40 ¬µV. The LP3986 features fast turn-on capabilities with a typical startup time of 200 ¬µs and includes overcurrent and thermal protection. It operates within a temperature range of -40¬8C to +125¬8C, making it suitable for a variety of environments. The product is housed in a micro SMD package, facilitating compact designs. Applications for the LP3986TL-2818 include CDMA and GSM cellular handsets, portable information appliances, and other portable battery applications.
