SPX3819 Datasheet | Exar

500mA Low-Noise LDO Voltage Regulator 500mA Low-Noise LDO Voltage Regulator August 2016 GENERAL DESCRIPTION The SPX3819 is a positive voltage regulator with a low dropout voltage and low noise output. In addition, this device offers a very low ground current of 800μA at 100mA output. The SPX3819 has an initial tolerance of less than 1% max and a logic patible ON/OFF switched input. When disabled, power consumption drops to nearly zero. Other key Features include reverse battery protection, current limit, and thermal shutdown. The SPX3819 includes a reference bypass pin for optimal low noise output performance. With its very low output temperature coefficient, this device also makes a superior low power voltage reference. The SPX3819 is an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and portable puters. It is available in several fixed output voltage options or with an adjustable output voltage. This device is...
