NCP585
Tri-Mode 300 mA CMOS
LDO Regulator with Enable
The NCP585 series of low dropout regulators are designed for portable battery powered applications which require precise output voltage accuracy, low quiescent current, and high ripple rejection. These devices feature an enable function which lowers current consumption significantly and are offered in the SOT23−5 and the HSON−6 packages, in fixed output voltages between 0.8 V and 3.3 V.
This series of devices have three modes. Chip Enable (CE mode), Fast Transient Mode (FT mode), and Low Power Mode (LP mode). Both the FT and LP mode are utilized via the ECO pin.
Features
• Tri−mode Operation • Low Dropout Voltage:
Typ 550 mV at 300 mA, Output Voltage = 0.9 V Typ 480 mV at 300 mA, Output Voltage = 1.
