NCP4589: Linear Voltage Regulator, LDO, Tri-Mode, 300 mA
The NCP4589 is a CMOS 300mA LDO which switches to a low power mode under light current loads. The device automatically switches back to a fast response mode as the output load increases above 3mA. The device can be placed in permanent fast mode through a mode select pin. NCP4589 comes in two output configurations: standard output and an auto-discharge configuration. The family is available in a variety of packages: SC-70-5 (SC88A), SOT23-5 and a small, ultra thin 1.2x1.2 mm XDFN. Output voltages are available in the range 0.8V to 4.0V in 100mV steps. Contact your local Sales office for a specific output voltage, package and discharge configuration.
特性- Iq is 55uA (typical) or 1.5uA in LP mode
- Good PSRR - 70dB typical
- Low dropout 230mV typ.
- Auto-discharge output available
| 优势- Trades slower transient response for lower power
- Excellent ripple rejection
- Extends battery life by excepting lower input voltages, lowers power dissipation.
- Trade off voltage lag vs. time to turn on
|
应用- Applications that are usually active but under light load
| 终端产品- Detectors, smoke alarms, HDD
- Cameras, monitors, LCD TVs
- Cable Boxes, DVD players, remote controls
