myAnalogFEATURES and BENEFITS
- Input voltage range: 2.3 V to 5.5 V
- Output voltage range: 1.2 V to 3.3 V
- Output current: 150 mA
- Low quiescent current
IGND = 11 μA with 0 μA load
IGND = 30 μA with 150 mA load - Low shutdown current: <1 μA
- Low dropout voltage
90 mV @ 150 mA load - High PSRR
70 dB @ 1 kHz at VOUT = 1.2 V
70 dB @ 10 kHz at VOUT = 1.2 V - Low noise: 40 μV rms at VOUT = 1.2 V
- See data sheet for additional features
