The l denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. Unless otherwise noted, VS = 5V, VCM = VOUT = VS/2, VSHDN = 5V,

RL to VS/2.

ELECTRICAL CHARACTERISTICS

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The inputs are protected by two series connected ESD protection

diodes to each power supply. The input current should be limited to less than

10mA. The input voltage should not exceed 300mV beyond the power supply.

Note 3: A heat sink may be required to keep the junction temperature below

the absolute maximum rating when the output is shorted indefinitely.

Note 4: The LTC2063I/LTC2064I/LTC2065I are guaranteed to meet

specified performance from –40°C to 85°C. The LTC2063H/LTC2064H/

LTC2065H are guaranteed to meet specified performance from –40°C

to 125°C.

Note 5: Thermal resistance varies with the amount of PC board metal

connected to the package. The specified values are for short traces

connected to the leads.

Note 6: These parameters are guaranteed by design. Thermocouple effects

preclude measurements of these voltage levels during automated testing.

VOS is measured to a limit determined by test equipment capability.

Note 7: Input bias current is only production tested at 5V. Input bias

current at 1.8V is expected to meet or exceed 5V specifications.

Note 8: Minimum specifications for these parameters are limited by noise

and the capabilities of the automated test system.
