1.5A LINEAR BUS TERMINATION REGULATOR
ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are those values beyond which the
device could be permanently damaged.

ELECTRICAL CHARACTERISTICS (Unless otherwise stated, these specifications apply T_A=25°C;
VCCA=VIN=+2.5V and VDDQ=+2.5V (Note 3)) maximum ratings are stress ratings only and functional device operation is not
implied.

Note 1: Operating range indicates conditions for which the device is intended to be functional, but does not guarantee specific
performance limits. For guaranteed specification and test conditions see Electrical Characteristics.
Note 2: At elevated temperatures, devices must be derated based on the thermal resistance. The SO-8 package must be derated
atθ_JA = 151℃/W junction to ambient with no heat sink.
Note 3: Limits are 100% production tested at 25℃. Limits over the operating temperature range are guaranteed through
correlation using Statistical Quality Control methods.
Note 4: VOS = VREF – VOUT
Note 5: Load regulation is tested by using a 10ms current pulse and measuring VOUT.
Note 6: Quiescent current defined as the current flow into VCCA.
Note 7: PG function but LP2995 does not have it. PG will be high as VTT is larger than 90% VREF, and PG will change to low
as VTT is lower than 85% VREF. PG also will be low as VTT is greater than 115% VREF, and PG will change to high as
VTT is lower than 110% VREF. It has both directions PG function.
