(1) Unless otherwise noted, all limits specified for V_IN = (V_ONOM + 1)V, I_L = 100 μA and C_L = 1μF for 5V versions and 2.2 μF for 3V and
3.3V versions. Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in
normal type apply for T_A = T_J = 25°C. Additional conditions for the 8-pin versions are FEEDBACK tied to V_TAP, OUTPUT tied to SENSE,
and V_SHUTDOWN ≤ 0.8V.
(2) Ensured and 100% production tested.
(3) A Military RETS specification is available on request. At time of printing, the LP2951-N RETS specification complied with the boldface
limits in this column. The LP2951-N LMC, NAC, or NAB may also be procured as Standard Military Drawing Spec #5962-3870501MGA,
MXA, or MPA.
(4) Ensured but not 100% production tested. These limits are not used to calculate outgoing AQL levels.
(5) All LP2950 devices have the nominal output voltage coded as the last two digits of the part number. In the LP2951 products, the 3.0V
and 3.3V versions are designated by the last two digits, but the 5V version is denoted with no code at this location of the part number
(refer to ordering information table).
(6) Output or reference voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
(7) 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.
(8) Line regulation for the LP2951-N is tested at 150°C for I_L = 1mA. For I_L = 100 μA and T_J = 125°C, line regulation is specified by design
to 0.2%. See TYPICAL PERFORMANCE CHARACTERISTICS for line regulation versus temperature and load current.
