SPX3819M5-L-5-0/TR 低压差稳压器

SPX3819M5-L-5-0/TR

低压差稳压器 500mA Low-Noise LDO Voltage Regulator

GENERAL DESCRIPTION SPX3819M5-L-5-0/TR

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 compatible 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  computers. It is available in several fixed  output voltage options or with an adjustable  output voltage.
