Regulator Input. 1.425V to 3.6V voltage range. Bypass to GND with at least 1μF
of ceramic capacitance. IN is high impedance when the LDO is shut down.
Internal Circuitry Supply Input. BIAS supplies the power for the internal circuitry.
3V to 5.5V voltage range.
Internally Connected. Connect I.C. directly to GND.
LDO Enable. Drive EN high to enable the LDO or connect to IN (BIAS for

the IC in low-power shutdown mode.
Soft-Start Input. For typical operation, connect a 0.1 μF capacitor from SS to GND.
