4 / 24 page  LP2960 SNVS112C – APRIL 1999 – REVISED APRIL 2013 www.ti.com Electrical Characteristics (continued) Limits in standard typeface are for TJ = 25°C, and limits in boldface type apply over the full operating temperature range. Unless otherwise specified: CIN = 4.7 μF, VIN = VO(NOM) + 1V, IL = 1 mA, COUT = 10 μF for 5V parts or COUT = 22 μF for 3.3V parts, Feedback pin is tied to VTAP pin, Output pin is tied to Sense pin, VS/D = 2V.

To express these thresholds in terms of output voltage change, multiply by the error amplifier gain which is VO/VREF = (R1 + R2)/R2 (see Basic Application Circuit). (11) Vshutdown ≤ 1.1V, VIN < 30V, VOUT = 0V. 4 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: LP2960 |
