Quiescent current is 50 µA typical — the regulator's own draw is low enough for battery-powered designs where the load spends most of its time in a light or sleep state. ## Protection set and package fit Built-in protection covers over-current, over-temperature, reverse polarity, short circuit, and includes a soft-start ramp — the reverse-polarity clamp is unusual at this current level and saves an external Schottky on the input if the supply can reverse-bias. Packaged in a 6-UFDFN (1.6 x 1.6 mm) with a supplier device package of 6-UTDFN — the exposed pad on the underside carries the thermal path to the PCB copper, so the board footprint should include a thermal via array under the pad to keep junction temperature within the -40 to 85 °C operating range. Enable pin (active-high) lets the system power down the regulator to near-zero quiescent current when the load is idle — the pin threshold is compatible with 1.8 V logic, so a low-voltage GPIO can control it directly.","metaTitle":"ISL9021AIRUMZ-T7A LDO Regulator, 3V Fixed, 250mA, 6-UTDFN","metaDescription":"Active Renesas LDO, 3V fixed output, 250mA, 0.25V dropout at full load, 50µA Iq, 6-UTDFN (1.6x1.6) package, -40 to 85°C.
