NCP154_15 Datasheet, PDF (1/18 Pages) ON Semiconductor – Dual 300 mA, Low IQ, Low Dropout, Dual Input Voltage Regulator

NCP154
Dual 300 mA, Low I_Q, Low
Dropout, Dual Input Voltage
Regulator
The NCP154 is 300 mA, Dual Output Linear Voltage Regulator that
offers two independent input pins and provides a very stable and
accurate voltage with ultra low noise and very high Power Supply
Rejection Ratio (PSRR) suitable for RF applications. The device
doesn’t require any additional noise bypass capacitor to achieve ultra
low noise performance. In order to optimize performance for battery
operated portable applications, the NCP154 employs the Adaptive
Ground Current Feature for low ground current consumption during
light-load conditions.
Features
• Operating Input Voltage Range: 1.9 V to 5.25 V
• Two Independent Input Voltage Pins
• Two Independent Output Voltage (for detail please refer to Ordering
Information)
