零件编号 : LD2982AM32R
功能 : VERY LOW DROP AND LOW NOISE VOLTAGE REGULATO WITH INHIBIT FUNCTION
制造商 : STMicroelectronics
The LD2982 is a 50 mA fixed output voltage regulator. The ultra low drop voltage and the low
quiescent current make them particularly suitable for low noise, low power applications, and in
battery powered systems.
In sleep mode quiescent current is less than 1 µA when INHIBIT
pin is pulled low. Shutdown logic control function is available on pin 3 (TTL compatible). This
means that when the device is used as local regulator, it is possible to put a part of the board in
standby, decreasing the total power consumption.
An external capacitor CBYP = 10 nF connected between bypass pin and GND reduce the noise to
