The LP3871ES-5.0 is a fast ultra-low dropout linear voltage regulator capable of delivering a guaranteed output current of 0.8A. It operates with an input supply voltage ranging from +2.5V to +7.0V and features an ultra-low dropout voltage, typically 240mV at 0.8A load current. The device has a low ground pin current of approximately 6mA at full load and a quiescent current of just 10nA in shutdown mode. Output voltage accuracy is specified at ±1.5% at room temperature and ±3.0% across all conditions. The LP3871ES-5.0 includes an error flag that indicates when the output voltage drops below 90% of its nominal value. It is available in a TO-263-5 package and is suitable for applications such as microprocessor power supplies, bus terminators, and battery-powered devices. The operating junction temperature range is from -40°C to +125°C, making it versatile for various environmental conditions.
