RESET/FB — 5 O/I This terminal is the feedback point for the adjustable option TPS72501. For all other options, this
terminal is the RESET output terminal. When used with a pullup resistor, this open-drain output
provides the active low RESET signal when the regulator output voltage drops more than 5% below
its nominal output voltage. The RESET delay time is typically 50 ms.
NC 4 — No connection
OUT 1 4 O Regulated output voltage
