LTC1555L-1.8 - SIM Power Supply and Level Translator
Internal level translators allow controllers operating with supplies as low as 1.425V to interface with 1.8V, 3V and 5V SIMs. A soft-start feature limits inrush current at turn-on, mitigating start-up problems that may result when the input is supplied by another low-power DC/DC converter. Battery life is maximized by 32µA operating current, and 1µA shutdown current. Board area is minimized by the miniature 16-pin narrow SSOP packages and the need for only three small external capacitors.
