NCV8154
Dual 300 mA, Low IQ, Low
Dropout, Dual Input Voltage
Regulator
The NCV8154 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 NCV8154 is
suitable for powering RF blocks of automotive infotainment systems
and other power sensitive device. Due to low power consumption the
NCV8154 offers high efficiency and low thermal dissipation.
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)
• Low IQ of typ. 55 mA per Channel
• High PSRR: 75 dB at 1 kHz
• Very Low Dropout: 140 mV Typical at 300 mA
• Thermal Shutdown and Current Limit Protections
• Stable with a 1 mF Ceramic Output Capacitor
• Available in DFN10 3 × 3 mm Package
• Active Output Discharge for Fast Output Turn-Off
• NCV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• These are Pb-free Devices
Typical Applications
• Applications Requiring Wettable Flanks for Enhanced Visual
Inspection
• Wireless LAN, Bluetooth®, ZigBee® Interfaces
• Automotive Infotainment Systems
