Product details
Overview
LP2986AIMM-3.0/NOPB from Texas Instruments is a micropower, 200-mA ultra-low-dropout linear voltage regulator in an 8-pin VSSOP package, delivering fixed 3.0 V output with ±0.5% accuracy (A grade), 180 mV typical dropout at 200 mA, and <1 µA quiescent current in shutdown - deployed in portable battery-powered systems requiring precision rail stability and low-power supervision.
For engineers reviewing the LP2986AIMM-3.0/NOPB datasheet, LP2986AIMM-3.0/NOPB pinout, LP2986AIMM-3.0/NOPB application, or LP2986AIMM-3.0/NOPB equivalent, this page delivers verified electrical specs, thermal behavior, ERROR flag timing thresholds, shutdown interface requirements, and fixed-output configuration details essential for low-noise, high-accuracy power management design.
Technical Context
The LP2986AIMM-3.0/NOPB uses a vertically integrated PNP (VIP) bipolar process to achieve ultra-low dropout (180 mV @ 200 mA) while maintaining tight output regulation (0.5% initial accuracy, 20 ppm/°C tempco) and low ground pin current (1 mA @ 200 mA). Its internal 1.23-V reference enables precise feedback control without external components when configured for fixed 3.0 V output via TAP–FEEDBACK and OUT–SENSE pin strapping.
It integrates an open-collector ERROR flag that asserts low when VOUT falls ≥5% below nominal, and a logic-compatible SHUTDOWN input (VH = 1.4 V min, VL = 0.55 V max) enabling sub-µA sleep mode. Thermal shutdown and current limiting protect against overload, with peak output capability up to 400 mA under transient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±0.5% (A grade) at 25°C; ±0.84% over −40°C to +125°C junction range - ensures stable MCU core or sensor bias rails without trimming. |
| Dropout Voltage | 180 mV typical at 200 mA load - enables regulation from 3.18 V input, critical for single-cell Li-ion or Li-poly systems near end-of-discharge. |
| Quiescent Current | 1 µA max in shutdown mode - extends battery life in always-on monitoring circuits such as smoke detectors or IoT edge nodes. |
| Ground Pin Current | 1 mA typical at 200 mA load - minimizes wasted power in ground path, improving efficiency vs. older LDOs with >5 mA GND current. |
| ERROR Flag Threshold | Asserts low when VOUT drops ≥5% below nominal - provides reliable undervoltage detection for system reset or fault logging without external comparators. |
| Input Voltage Range | 2.1 V to 16 V operating - supports wide-input applications including automotive accessory rails, industrial 12-V supplies, and multi-cell battery packs. |
| Thermal Resistance (RθJA) | 156.5°C/W for VSSOP-8 package - requires minimal PCB copper area for thermal management in space-constrained handheld designs. |
Pinout & Package
LP2986AIMM-3.0/NOPB is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, with exposed pad not present (VSSOP variant lacks thermal pad). Pin functions are identical across SOIC, VSSOP, and WSON packages per TI's datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: GROUND | Power return reference | Common analog/digital ground node; connects to PCB ground plane to stabilize regulation and minimize noise coupling. |
| 2: FEEDBACK | Regulation error sense input | Tied to TAP pin for fixed 3.0 V operation; accepts external resistor divider for adjustable outputs - sets output voltage via internal 1.23-V reference. |
| 3: TAP | Internal divider mid-point output | Connected to FEEDBACK to select factory-trimmed 3.0 V output; unused in adjustable configurations - enables pin-strapped fixed-voltage mode without external resistors. |
| 4: IN | Unregulated input supply | Accepts 2.1–16 V input; requires ≥2.2 µF ceramic capacitor placed ≤12.7 mm from pin to suppress high-frequency noise and ensure stability. |
| 5: OUT | Regulated output | Delivers 3.0 V at up to 200 mA; requires ≥4.7 µF ceramic output capacitor with ESR < 1 Ω to maintain loop stability across temperature and load. |
| 6: SENSE | Remote output sensing input | Tied to OUT for local regulation; enables Kelvin sensing in high-precision applications by connecting directly to load to reject PCB trace IR drop. |
| 7: ERROR | Open-collector fault indicator | Drives low when VOUT falls ≥5%; requires external pull-up to VOUT or another supply (≤16 V); sinks up to 300 µA - used for system-level reset or status signaling. |
| 8: SHUTDOWN | Active-high enable control | Pull ≥1.4 V to enable; ≤0.55 V to disable; slew rate ≥40 mV/µs required to avoid metastability - allows microcontroller GPIO to manage power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 180 mV at full 200 mA load - sustains regulation down to 3.18 V input, extending usable battery capacity in 3.3-V systems. |
| High-accuracy fixed output | ±0.5% initial tolerance at 25°C for 3.0 V version - eliminates need for post-production calibration in precision analog or RF subsystems. |
| Integrated ERROR flag | Detects ≥5% VOUT sag with built-in comparator - replaces discrete supervisor ICs in compact portable designs, reducing BOM count. |
| Micropower shutdown | <1 µA quiescent current when disabled - preserves battery charge during long idle periods in wearables and remote sensors. |
| Robust protection suite | Thermal shutdown + current limit + reverse-input protection - prevents damage during hot-swap, short-circuit, or overtemperature events without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F3TAV50 | Automotive-grade AEC-Q100 qualified; 500-mA output; higher 300 mV dropout; integrated watchdog timer. | Designed for under-hood automotive use with extended temp range (−40°C to +150°C); includes safety features absent in LP2986AIMM-3.0/NOPB. | Select when functional safety (ASIL-B) compliance or higher current is required; not drop-in due to different pinout and control logic. |
| TPS7A2030PDQNR | CMOS-based; 300-mA output; 170 mV dropout; 25 µA quiescent current active; no ERROR flag or SHUTDOWN pin. | Optimized for ultra-low-noise (7 µVRMS) and fast transient response; lacks supervision features but offers better PSRR (70 dB @ 1 kHz). | Prefer for noise-sensitive analog rails where supervision is handled externally; incompatible pinout and missing ERROR/SHUTDOWN signals prevent direct replacement. |
Compared with TLS850F3TAV50 and TPS7A2030PDQNR, the LP2986AIMM-3.0/NOPB uniquely balances micropower shutdown (<1 µA), integrated ERROR flag, and 0.5% fixed-output accuracy in a legacy-pinout VSSOP package - making it optimal for cost-sensitive, non-automotive portable systems needing supervision without added ICs.

FAQ
What is the maximum input voltage rating for LP2986AIMM-3.0/NOPB?
The LP2986AIMM-3.0/NOPB has an absolute maximum input voltage rating of 16 V, with recommended operating range from 2.1 V to 16 V. Exceeding 16 V may cause permanent damage. This wide input range allows LP2986AIMM-3.0/NOPB to operate from single-cell Li-ion (up to 4.2 V), multi-cell alkaline stacks, or 12-V automotive auxiliary rails with appropriate transient suppression.
Does LP2986AIMM-3.0/NOPB require external capacitors, and what values are recommended?
Yes, LP2986AIMM-3.0/NOPB requires both input and output capacitors for stability. A minimum 2.2 µF ceramic capacitor must be placed ≤12.7 mm from the IN pin to ground, and a minimum 4.7 µF ceramic capacitor with ESR < 1 Ω is required on the OUT pin. These values are validated in TI's datasheet for all operating conditions and ensure robust transient response and ripple rejection.
How does the ERROR pin on LP2986AIMM-3.0/NOPB function, and what external components are needed?
The ERROR pin on LP2986AIMM-3.0/NOPB is an open-collector output that pulls low when VOUT drops ≥5% below nominal. It requires an external pull-up resistor to VOUT or another supply (≤16 V) and can sink up to 300 µA. No pull-up is needed if the pin is unused - it may be left floating. This feature enables LP2986AIMM-3.0/NOPB to serve as a self-contained undervoltage supervisor.
Can LP2986AIMM-3.0/NOPB be used in adjustable-output configurations?
No - LP2986AIMM-3.0/NOPB is a fixed-output variant configured internally for 3.0 V. While the base LP2986 family supports adjustable outputs via external resistors on the FEEDBACK pin, the AIMM-3.0/NOPB suffix denotes factory-trimmed 3.0 V operation with TAP and SENSE pins pre-configured for that voltage. Using it in adjustable mode would violate its specified accuracy and is not supported.
What thermal performance can be expected from LP2986AIMM-3.0/NOPB in its VSSOP-8 package?
In the 8-pin VSSOP (DGK) package, LP2986AIMM-3.0/NOPB has a junction-to-ambient thermal resistance (RθJA) of 156.5°C/W under JEDEC High-K board conditions. At 200 mA load with 3.18 V input (180 mV dropout), power dissipation is ~36 mW, resulting in ~5.6°C junction rise above ambient - well within safe limits without heatsinking in typical handheld PCB layouts.
