SGLS326C – APRIL 2006 – REVISED FEBRUARY 2009 over operating temperature range (TA = –55°C to 125°C), VIN = VOUT(nom) + 0.5 V (1), I OUT = 10 mA, VEN = 1.7 V, and COUT = 0.1 µF (unless otherwise noted). Typical values are at TJ = 25°C.

(2) For VOUT(nom) < 1.6 V, when VIN ≤ 1.6 V, the output locks 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) VDO is not measured for the TPS73615 (VOUT(nom) = 1.5 V) since minimum VIN = 1.7 V. (4) See the Applications section for more information.
