LT3010/LT3010-5
APPLICATIONS INFORMATION
above 3? is unsuitable for use with the LT3010H. Ceramic
capacitor manufacturers (Murata, AVX, TDK, and Vishay
Vitramon at this writing) now offer ceramic capacitors that
are rated to 150°C using an X8R dielectric. Device instability
will occur if output capacitor value and ESR are outside
design limits at elevated temperature and operating DC
voltage bias (see information on capacitor characteristics
under Output Capacitance and Transient Response). Check
each passive component for absolute value and voltage
ratings over the operating temperature range.
Leakages in capacitors or from solder flux left after in-
sufficient board cleaning adversely affects low quiescent
current operation. Consider junction temperature increase
due to power dissipation in both the junction and nearby
components to ensure maximum specifications are not
violated for the LT3010H or external components.
Protection Features
The LT3010 incorporates several protection features which
make it ideal for use in battery-powered circuits. In ad-
dition to the normal protection features associated with
monolithic regulators, such as current limiting and thermal
limiting, the device is protected against reverse-input volt-
ages, and reverse voltages from output to input.
Current limit protection and thermal overload protection
are intended to protect the device against current overload
conditions at the output of the device. For normal opera-
tion, the junction temperature should not exceed 125°C
(LT3010E/LT3010MP) or 140°C (LT3010H).
The input of the device will withstand reverse voltages
of 80V. Current flow into the device will be limited to less
than 6mA (typically less than 100μA) and no negative
voltage will appear at the output. The device will protect
both itself and the load. This provides protection against
batteries which can be plugged in backward.
The ADJ pin of the adjustable device can be pulled above
or below ground by as much as 7V without damaging the
device. If the input is left open circuit or grounded, the
ADJ pin will act like an open circuit when pulled below
ground, and like a large resistor (typically 100k) in series
with a diode when pulled above ground. If the input is
powered by a voltage source, pulling the ADJ pin below
the reference voltage will cause the device to try and force
the current limit current out of the output. This will cause
the output to go to a unregulated high voltage. Pulling
the ADJ pin above the reference voltage will turn off all
output current.
In situations where the ADJ pin is connected to a resistor
divider that would pull the ADJ pin above its 7V clamp volt-
age if the output is pulled high, the ADJ pin input current
must be limited to less than 5mA. For example, a resistor
divider is used to provide a regulated 1.5V output from the
1.22V reference when the output is forced to 60V. The top
resistor of the resistor divider must be chosen to limit the
current into the ADJ pin to less than 5mA when the ADJ
pin is at 7V. The 53V difference between the OUT and ADJ
pins divided by the 5mA maximum current into the ADJ
pin yields a minimum top resistor value of 10.6k.
