NOM + 1 V), I
L
= 100 µA and C
L
= 1 µF for
5-V versions and 2.2 µF for 3-V and 3.3-V versions. Additional conditions for the 8-pin versions are FEEDBACK tied to VTAP, OUTPUT
tied to SENSE, and V
SHUTDOWN
≤
0.8 V.
A Military RETS specification is available on request.
All LP2950 devices have the nominal output voltage coded as the last two digits of the part number. In the LP2951 products, the 3-V
and 3.3-V versions are designated by the last two digits, but the 5-V version is denoted with no code at this location of the part number
(refer to the
Package Option Addendum
at end of data sheet).
Ensured and 100% production tested.
Ensured but not 100% production tested. These limits are not used to calculate outgoing AQL levels.
Output or reference voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to
heating effects are covered under the specification for thermal regulation.
Line regulation for the LP2951-N is tested at 150°C for I
L
= 1 mA. For I
L
= 100 µA and T
J
= 125°C, line regulation is specified by design
to 0.2%. See
for line regulation versus temperature and load current.
