Data Sheet (Rev. B) Product Selection Table

Viewing:

Overview

Input voltage range: 2.3 V to 5.5 V
Output voltage range: 1.2 V to 3.3 V
Low quiescent current:
I_GND = 11 μA with zero load
I_GND = 22 μA with 100 mA load
Low shutdown current: <1 μA
Low dropout voltage
60 mV @ 100 mA load

Output current: 100 mA
High PSRR:
73 dB @ 1 kHz at V_OUT= 1.2 V
70 dB @ 10 kHz at V_OUT= 1.2 V
Low noise: 40 μV rms at V_OUT = 1.2 V
No noise bypass capacitor required
Initial accuracy: ±1%
Stable with small 1 μF ceramic output capacitor
