It is part of the LP3982 family of low-dropout regulators (LDOs) designed for noise-sensitive and battery-powered applications where a clean, regulated rail is needed from a 6 V maximum input. The key parametric for the BOM-fit is the dropout voltage: 0.22 V maximum at 200 mA load. For a 3.3 V input bus, that leaves just 80 mV of headroom at the 200 mA point — marginal if the input rail sags under system load. A 3.6 V or 5 V input provides comfortable margin. ## Quiescent current and protection suite Quiescent current (Iq) is 270 µA typical. For a device that spends most of its time in active regulation, this Iq is the baseline current draw from the input supply regardless of load — it sets the floor for system power consumption in always-on domains. The Enable control feature (active-high) lets the system shut down the regulator completely, dropping Iq to near zero when the 3.0 V rail is not needed. Protection features include over-current, over-temperature, and reverse polarity. The over-current limit protects the pass element and downstream circuitry during a fault or short-circuit event. Over-temperature shutdown prevents thermal runaway if the device is operated beyond its power dissipation capability. Reverse polarity protection guards against accidental reverse battery connection on the input, a common concern in automotive and industrial environments. ## Package options and board integration The LP3982IMM-3.0/NOPB is offered in an 8-VSSOP package (the supplier device package designation for the 8-TSSOP / 8-MSOP footprint, 3.00 mm width). The small footprint (roughly 3 x 3 mm) makes it a fit for space-constrained designs like portable instruments, wireless modules, and compact sensor boards. The TR format is the standard for automated pick-and-place assembly; CT is useful for prototyping and low-volume builds where a full reel is not needed.","metaTitle":"Texas Instruments LP3982IMM-3.0/NOPB LDO, 300mA, 3.0V Fixed","metaDescription":"Texas Instruments LP3982IMM-3.0/NOPB LDO regulator, 300mA output, 3.0V fixed, 0.22V dropout at 200mA, 270µA Iq, -40 to 85°C, 8-VSSOP.
