10 µA quiescent current — the battery-life anchor
The TPS61120RSARG4 is a power management IC from Texas Instruments, designed for handheld and mobile devices where standby power dominates the battery budget. Its 10 µA supply current sets the quiescent floor — every microamp above that comes from the load, not the regulator itself.
Industrial temperature range — outdoor and portable gear
The industrial temp grade means the 10 µA quiescent current is guaranteed across the range, not just at 25°C — critical when the device sits on a hot dash or a cold loading dock.
16-QFN with exposed pad — layout checklist
The 0.50 mm pitch limits breakout to a 4-layer board if all 16 pins are used; two-layer designs work if only the inner rows are routed. Confirm the supplier device package (16-QFN 4x4) matches the land pattern in your layout tool — the exposed pad size and via count directly affect RthJA.
Sourcing and lifecycle — no LTB planning needed
TI lists the TPS61120RSARG4 as Active.
