4 / 32 page TPS736xx SBVS038T – SEPTEMBER 2003 – REVISED AUGUST 2010 www.ti.com ELECTRICAL CHARACTERISTICS Over operating temperature range (TJ = –40°C to +125°C), VIN = VOUT(nom) + 0.5V (1), I OUT = 10mA, VEN = 1.7V, and COUT = 0.1mF, unless otherwise noted. Typical values are at TJ = +25°C.

(2) For VOUT(nom) < 1.6V, when VIN ≤ 1.6V, the output will lock to VIN and may result in a damaging over-voltage level on the output. To avoid this situation, disable the device before powering down the VIN. (3) TPS73601 is tested at VOUT = 2.5V. (4) Tolerance of external resistors not included in this specification. (5) VDO is not measured for fixed output versions with VOUT(nom) < 1.8V. (6) Fixed-voltage versions only; refer to Applications section for more information. 4 Submit Documentation Feedback Copyright © 2003–2010, Texas Instruments Incorporated |
