(2) Dropout is only valid when VOUT ≥ 2.8 V because of the minimum input voltage limits. (3) Measured with VIN = VOUT + 3 V for VOUT ≤ 2.5 V. Measured with VIN = VOUT + 2.5 V for VOUT > 2.5 V. (4) Startup time = time from EN assertion to 0.95 × VOUT(NOM) and load = 47 Ω. Copyright © 2012–2013, Texas Instruments Incorporated Submit Documentation Feedback 3 |
