CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
3. Extended operation at these conditions may compromise reliability. Exceeding these limits will result in damage. Recommended operating conditions
define limits where specifications are guaranteed.
4. Refer to “Thermal Guidelines” on page 15.
5. Product capability established by initial characterization. The "EH" version is acceptance tested on a wafer by wafer basis to 50 krad(Si) at low dose
rate.
6. Specify EVAL test conditions for SET/SEB/SEL here.
7. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379
8. For θ_JC, the “case temp” location is the center of the package underside.
9. The device can work down to V_OUT = 0.8V; however, the SET performance of < ±5% at LET = 86MeV.cm²/mg is guaranteed at V_OUT = >1.5V only. SET
tests performed with 220µF 10V 25mΩ and 0.1µF CDR04 capacitor on the input and output.
Electrical Specifications Unless otherwise noted, all parameters are guaranteed over the following specified conditions:
V_IN = V_OUT + 0.4V, V_OUT = 1.8V, C_IN = C_OUT = 220µF 25mΩ and 0.1µF X7R, T_J = +25°C, I_L = 0A. Applications must follow thermal guidelines of
the package to determine worst-case junction temperature (see Note 13). Boldface limits apply over the operating temperature range, -55°C to
+125°C. Pulse load techniques used by ATE to ensure T_J = T_A defines guaranteed limits.
