3 / 22 page ![]() LM4121 www.ti.com SNVS073C – APRIL 2000 – REVISED APRIL 2013 Operating Range (1) Storage Temperature Range −65°C to +150°C Ambient Temperature Range −40°C to +85°C Junction Temperature Range −40°C to +125°C (1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see Electrical Characteristics - LM4121-1.250V and Electrical Characteristics - LM4121-ADJ tables. The ensured specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Electrical Characteristics LM4121-1.250V Unless otherwise specified VIN = 3.3V, ILOAD = 0, COUT = 0.01µF, TA = Tj = 25°C. Limits with standard typeface are for Tj = 25°C, and limits in boldface type apply over the −40°C ≤ TA ≤ +85°C temperature range.

Limits over the operating temperature range are ensured through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate TI's Averaging Outgoing Quality Level (AOQL). (2) Typical numbers are at 25°C and represent the most likely parametric norm. (3) Thermal hysteresis is defined as the change in +25°C output voltage before and after exposing the device to temperature extremes.
