6 / 31 page 6 TPSM82480 SLVSDT1 – JULY 2017 www.ti.com Product Folder Links: TPSM82480 Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated Electrical Characteristics (continued) over operating junction temperature range (TJ = –40°C to 125°C) and VIN = 2.4 V to 5.5 V. Typical values at VIN = 3.6 V and TJ = 25°C (unless otherwise noted). PARAMETER TEST CONDITIONS MIN TYP MAX UNIT (1) The output voltage accuracy in Power Save Mode can be improved by increasing the output capacitor value, reducing the output voltage ripple. (2) For detailed information on output discharge see Active Output Discharge.
