SNVS552B – MARCH 2008 – REVISED APRIL 2013
Electrical Characteristics
LM4030-2.5 (VOUT = 2.5V)
Limits in standard type are for TJ = 25°C only, and limits in boldface type apply over the junction temperature (TJ) range of -
40°C to +125°C. Minimum and Maximum limits are ensured through test, design, or statistical correlation. Typical values
represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only.

Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control.
(2)
Typical numbers are at 25°C and represent the most likely parametric norm.
(3)
Temperature coefficient is measured by the "Box" method; i.e., the maximum
ΔVREF is divided by the maximum ΔT.
(4)
Long term stability is VREF @25°C measured during 1000 hrs. This measurement is taken for IR = 500 µA.
(5)
Thermal hysteresis is defined as the change in +25°C output voltage before and after cycling the device from (-40°C to 125°C) eight
times.
(6)
Low frequency peak-to-peak noise measured using first-order 0.1 Hz HPF and second-order 10 Hz LPF.
