4 / 30 page  TPS796 SLVS351O – SEPTEMBER 2002 – REVISED NOVEMBER 2013 www.ti.com ELECTRICAL CHARACTERISTICS Over recommended operating temperature range (TJ = –40°C to +125°C), VEN = VIN,, VIN = VOUT(nom) + 1 V (1), I OUT = 1mA, COUT = 10μF, and CNR = 0.01μF, unless otherwise noted. Typical values are at +25°C.

TPS79650 is tested at VIN = 5.5V. (2) Tolerance of external resistors not included in this specification. (3) VDO is not measured for TPS79618 and TPS79625 because minimum VIN = 2.7V. (4) For adjustable version, this applies only after VIN is applied; then VEN transitions high to low. 4 Submit Documentation Feedback Copyright © 2002–2013, Texas Instruments Incorporated |
