Features
General Description
• Output voltage
2.5/2.7/2.8/3.0/3.3/4.5/5.0V
• Output current
150mA
• Output noise voltage 35μVrmstyp.
• No-load input current 90μA typ.
• I/O voltage difference 0.1V typ.(Io=50mA)
• Ripple rejection ratio 70dB typ.
• Bulit-in On/Off control
The AT1201 is a low-noise, low-dropout,
low-quiescent-current linear regulator designed for
battery-powered applications. The output voltage
precision is within ±2﹪and output currents of up
to 150mA;the input/output voltage difference at
50mA is only 0.1V.
Applications
• Cordless phones
• Portable phones, PHS
• Other battery operating system
