I.C.
FUNCTION
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
5

EN
MAX15028) for always-on operation. Drive EN low to disable the LDO and place
the IC in low-power shutdown mode.
Soft-Start Input. For typical operation, connect a 0.1μF capacitor from SS to

SS
GND. The soft-start timing is dependent on the value of this capacitor. See the
Soft-Start section.
Feedback Input. Connect FB to the center of a resistor-divider connected

between OUT and GND to set the output voltage. See the Programming the
Output Voltage section.

Regulator Output. Bypass OUT to GND with at least 4.7μF of ceramic
capacitance for 1A load operation.
Exposed Pad. Connect EP to GND and a large copper ground plane to facilitate
package power dissipation.
