Product details
Overview
LP2986AIMM-5.0/NOPB from Texas Instruments is a micropower, ultra-low-dropout linear voltage regulator delivering 200 mA at fixed 5.0 V output with 0.5% accuracy (A grade), 180 mV dropout at full load, and <1 µA quiescent current in shutdown - deployed in battery-powered portable electronics requiring precision, low-noise, and thermal robustness.
For engineers reviewing the LP2986AIMM-5.0/NOPB datasheet, LP2986AIMM-5.0/NOPB pinout, LP2986AIMM-5.0/NOPB application, or LP2986AIMM-5.0/NOPB equivalent, key selection criteria include guaranteed 200-mA output under 16-V input, integrated ERROR flag for supply monitoring, remote sensing capability via SENSE pin, and SOIC-8 packaging compatible with industrial temperature range (−40°C to +125°C).
Technical Context
The LP2986AIMM-5.0/NOPB uses a vertically integrated PNP (VIP) bipolar process to achieve ultra-low dropout (180 mV @ 200 mA) while maintaining high DC accuracy and low ground pin current (1 mA @ 200 mA). Its internal 1.23-V reference enables precise fixed-output regulation without external components when configured with TAP–FEEDBACK and OUT–SENSE ties.
It integrates dual functional blocks: a precision error amplifier with remote-sense feedback path and an open-collector ERROR comparator that asserts low when VOUT falls >5% below nominal. Shutdown control is active-high with defined turn-on/turn-off thresholds (VH = 1.4 V, VL = 0.55 V) and requires ≥40 mV/µs slew rate to avoid metastability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±0.5% (A grade) at 25°C; ±0.8% over −40°C to +125°C - ensures stable logic supply for microcontrollers and sensors. |
| Dropout Voltage | 180 mV typical at 200 mA load - enables operation down to VIN = 5.18 V, critical for single-cell Li-ion or multi-cell alkaline systems. |
| Quiescent Current | 1 µA max in shutdown mode - extends battery life in always-on standby applications like real-time clocks or memory retention. |
| Ground Pin Current | 1 mA typical at 200 mA load - minimizes wasted power and improves efficiency vs. older LDOs with higher GND current. |
| ERROR Flag Threshold | Asserts low when VOUT drops >5% below nominal - provides reliable undervoltage detection without external supervisor IC. |
| Input Voltage Range | 2.1 V to 16 V - supports wide-input industrial and automotive auxiliary rails, including unregulated 12-V systems. |
| Thermal Protection | Integrated overtemperature shutdown - prevents damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
LP2986AIMM-5.0/NOPB is packaged in an 8-pin SOIC (D package), body size 4.90 mm × 3.91 mm, with standard lead pitch and surface-mount compatibility. Thermal performance is characterized with RθJA = 114.4°C/W on JEDEC High-K board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GROUND (Pin 1) | Power return reference | Primary ground connection for regulator core and error amplifier; must be low-impedance to minimize noise coupling. |
| FEEDBACK (Pin 2) | Voltage sense input | Connects to internal 1.23-V reference; tied to TAP for fixed 5.0-V operation or external divider for adjustable output. |
| TAP (Pin 3) | Internal divider tap | Provides mid-point of internal resistive network; tied to FEEDBACK to select factory-trimmed 5.0-V output. |
| IN (Pin 4) | Unregulated input supply | Accepts 2.1–16 V input; requires ≥2.2 µF ceramic capacitor placed within 12.7 mm of pin for stability. |
| OUT (Pin 5) | Regulated output | Delivers up to 200 mA at 5.0 V; connects to SENSE for fixed-mode operation and remote sensing. |
| SENSE (Pin 6) | Remote output sense | Monitors load-side voltage to compensate for PCB trace IR drop; tied to OUT for local sensing in fixed mode. |
| ERROR (Pin 7) | Open-collector fault flag | Sinks up to 300 µA when VOUT drops >5%; requires external pull-up to VOUT or another rail ≤16 V. |
| SHUTDOWN (Pin 8) | Active-high enable | Pull ≥1.4 V to enable; ≤0.55 V to enter <1-µA shutdown; slew rate ≥40 mV/µs required for clean transition. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 180 mV at 200 mA enables operation from marginal input sources (e.g., aging batteries or unregulated supplies). |
| 0.5% output accuracy (A grade) | Guaranteed at 25°C and validated across temperature - eliminates need for post-regulation trimming in precision analog circuits. |
| Integrated ERROR flag | Dedicated open-collector output with 5% undervoltage threshold - replaces discrete supervisor + comparator in space-constrained designs. |
| Remote sensing (SENSE pin) | Compensates for voltage drop between OUT pin and load - maintains regulation accuracy at point-of-load in high-current PCB traces. |
| Micropower shutdown | <1 µA quiescent current in shutdown - meets stringent energy budgets for IoT edge nodes and wearable devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LP2985AIMM-5.0/NOPB | 150-mA rated output, identical 5.0-V A-grade accuracy and 180-mV dropout, but lacks ERROR flag and SENSE pin. | No built-in undervoltage monitoring or remote sensing - requires external supervisor for fault detection. | Select when cost sensitivity outweighs need for integrated supervision and load-side regulation. |
| TLS850F2T/V33 | Automotive-qualified 5.0-V LDO with 250-mA output, integrated watchdog and reset logic, but higher 300-mV dropout and no SENSE pin. | Designed for ASIL-B automotive domains; includes fail-safe features not needed in consumer portable gear. | Choose only for automotive applications requiring AEC-Q100 qualification and system-level safety monitoring. |
Compared with LP2985AIMM-5.0/NOPB, the LP2986AIMM-5.0/NOPB adds critical supervision and sensing capabilities at minimal cost premium; versus TLS850F2T/V33, it offers lower dropout and simpler integration for non-automotive use cases where qualification overhead is unnecessary.

FAQ
What is the maximum input voltage rating for the LP2986AIMM-5.0/NOPB?
The LP2986AIMM-5.0/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 risks permanent damage. The device is designed to operate reliably across this full range while maintaining 5.0-V output regulation and thermal protection functionality.
Does the LP2986AIMM-5.0/NOPB require external capacitors, and what values are recommended?
Yes, the LP2986AIMM-5.0/NOPB requires an input capacitor ≥2.2 µF and an output capacitor ≥4.7 µF, both ceramic or tantalum. These values ensure stability across load and temperature. The datasheet specifies 2.2 µF on IN and 4.7 µF on OUT as minimums; larger values improve transient response but do not harm operation. Placement within 12.7 mm of respective pins is critical.
How does the ERROR pin on the LP2986AIMM-5.0/NOPB function, and what external component is needed?
The ERROR pin on the LP2986AIMM-5.0/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. The pin sinks up to 300 µA. If unused, it may be left floating - no pull-up is mandatory unless fault signaling is implemented in the design.
Can the LP2986AIMM-5.0/NOPB be used in adjustable-output configurations, or is it fixed-only?
The LP2986AIMM-5.0/NOPB supports both fixed and adjustable output modes. In fixed mode (5.0 V), tie FEEDBACK to TAP and OUT to SENSE. For adjustable output (2.1–16 V), disconnect those ties and connect FEEDBACK to an external resistor divider from OUT to GROUND - enabling user-defined voltages while retaining all other LP2986AIMM-5.0/NOPB features.
What thermal considerations apply to the LP2986AIMM-5.0/NOPB in SOIC-8 package?
The LP2986AIMM-5.0/NOPB in SOIC-8 (D package) has RθJA = 114.4°C/W on JEDEC High-K board. At 200 mA and 16-V input, worst-case power dissipation is ~2.2 W, raising junction temperature significantly. Adequate copper area, thermal vias, and airflow are essential. Thermal shutdown activates if TJ exceeds 160°C, protecting the device but interrupting operation.
