The SPX3819R2-L-1-2/TR from Sipex is a low-noise, positive LDO (Low Dropout) voltage regulator designed for battery-powered applications. It features a low dropout voltage of 340mV at full load and a low quiescent current of 90µA, with zero off-mode current for power efficiency.
This regulator offers high accuracy with a 1% initial tolerance and can deliver up to 500mA of output current. It includes essential protection features such as reverse battery protection, current limit, and thermal shutdown. The device is available in fixed output voltage options, including 1.2V, and also offers an adjustable output voltage option.
The SPX3819 series is suitable for portable consumer equipment, instrumentation, and industrial applications. It is offered in multiple package types, including 5-pin SOT-23, 8-pin SOIC, and 8-pin DFN, all of which are surface mountable.
Key electrical characteristics include an input voltage range of 2.5V to 16V and a low output noise of 40µV possible. The device also boasts a very low output temperature coefficient, making it suitable as a low-power voltage reference.
