8 / 38 page LTC3676/LTC3676-1 8 3676ff For more information www.linear.com/LTC3676 Typical perForMance characTerisTics Standby IVIN vs VIN LDO2 to LDO4 IVIN vs VIN Step-Down Switching Regulator IVIN vs VIN elecTrical characTerisTics Note 3: The LTC3676 includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature will exceed 150°C when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability. Note 4: Dropout voltage is defined as (VIN – VLDO1) for LDO1 or (VIN_Lx – VLDOx) for other LDOs when VLDOx is 3% lower than VLDOx measured with VIN = VIN_Lx = 4.3V.

Note 6: Soft-Start measured in test mode with regulator error amplifier in unity-gain mode. Note 7: The switching regulator PMOS and NMOS on-resistance is guaranteed by correlation to wafer level measurements.
