NCP152
Dual 150 mA, Low IQ, Low
Dropout Voltage Regulator
The NCP152 is 150 mA, Dual Output Linear Voltage Regulator that
provides a very stable and accurate voltage with very low noise and
high Power Supply Rejection Ratio (PSRR) suitable for RF
applications. The device doesn’t require any additional noise bypass
capacitor to achieve very low noise performance. In order to optimize
performance for battery operated portable applications, the NCP152
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 Output Voltages:
(for details please refer to the Ordering Information section)
• Very Low Dropout: 150 mV Typical at 150 mA
• Low IQ of typ. 50 mA per Channel
• High PSRR: 75 dB at 1 kHz
• Two Independent Enable Pins
• Thermal Shutdown and Current Limit Protections
• Stable with a 0.22 mF Ceramic Output Capacitor
• Available in XDFN6 1.2 x 1.2 mm Package
• Active Output Discharge for Fast Output Turn−Off
• These are Pb−Free Devices
Typical Applications
• Smartphones, Tablets, Wireless Handsets
• Wireless LAN, Bluetooth®, ZigBee® Interfaces
• Other Battery Powered Applications
