Note 1:
The maximum junction temperature of the LM110 is 150
§
C, of the LM210 is 100
§
C, and of the LM310 is 85

C. For operating at elevated temperatures,
devices in the HO8 package must be derated based on a thermal resistance of 165
§
C/W, junction to ambient, or 22
§
C/W, junction to case. The thermal resistance
of the dual-in-line package is 100
§
C/W, junction to ambient.
Note 2:
For supply voltages less than
g
15V, the absolute maximum input voltage is equal to the supply voltage.
Note 3:
Continuous short circuit for the LM110 and LM210 is allowed for case temperatures to 125
§
C and ambient temperatures to 70

Note 5:
Increased output swing under load can be obtained by connecting an external resistor between the booster and V
b
terminals. See curve.
Note 6:
Refer to RETS110X for LM110H, LM110J military specifications.
Application Hint
The input must be driven from a source impedance of typically 10 k
X
(5 k
X
min.) to maintain stability. The total source
impedance will be reduced at high frequencies if there is stray capacitance at the input pin. In these cases, a 10 k
X
resistor
should be inserted in series with the input, physically close to the input pin to minimize the stray capacitance and prevent
oscillation.
