SPX3819M5-L/TR 低压差稳压器

SPX3819M5-L/TR

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

GENERAL DESCRIPTION  

The SPX3819M5-L/TR 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.
