Product details
Overview
LP2986AIMM-3.3/NOPB from Texas Instruments is a micropower, ultra-low-dropout linear voltage regulator delivering a precise 3.3 V output at up to 200 mA with 0.5% initial accuracy (A grade), 180 mV typical dropout at full load, and <1 µA quiescent current in shutdown - designed for battery-powered portable electronics requiring stable low-noise supply rails.
For engineers reviewing the LP2986AIMM-3.3/NOPB datasheet, LP2986AIMM-3.3/NOPB pinout, LP2986AIMM-3.3/NOPB application, or LP2986AIMM-3.3/NOPB equivalent, key selection considerations include its fixed 3.3 V output configuration, integrated ERROR flag with 5% undervoltage detection, thermal/overcurrent protection, and compatibility with ceramic output capacitors ≥4.7 µF.
Technical Context
The LP2986AIMM-3.3/NOPB uses a vertically integrated PNP (VIP) bipolar process to achieve ultra-low dropout (180 mV @ 200 mA) while maintaining high precision (±0.5% at 25°C, ±0.7% over −40°C to +125°C) and low ground pin current (1 mA @ 200 mA). Its internal resistive divider is factory-configured for 3.3 V output, eliminating external feedback components when used in fixed-voltage mode.
It integrates an open-collector ERROR flag that asserts low when VOUT falls >5% below nominal, a logic-compatible SHUTDOWN input (active-high, VH = 1.4 V min), and robust protection including thermal shutdown and current limiting (400 mA peak, short-circuit protected). The device operates across 2.1 V to 16 V input and supports remote sensing via SENSE pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V, ±0.5% accuracy at 25°C (A grade), ±0.7% over full temperature range - enables direct replacement of standard 3.3 V logic supplies without trimming. |
| Max Output Current | 200 mA continuous - sufficient for powering microcontrollers, sensors, and interface ICs in portable systems. |
| Dropout Voltage | 180 mV typical at 200 mA load - allows operation from single-cell Li-ion (3.0 V min) or 3.3 V rail with margin. |
| Quiescent Current | <1 µA in shutdown, 1–2.1 mA at 200 mA load - extends battery life in always-on or sleep-mode applications. |
| Ground Pin Current | 1 mA typical at 200 mA load - low and stable, minimizing wasted power and improving efficiency at high loads. |
| ERROR Flag Threshold | Asserts low when VOUT drops >5% below 3.3 V - provides reliable system-level undervoltage monitoring without external supervisor IC. |
| Input Voltage Range | 2.1 V to 16 V - supports wide-input industrial and automotive auxiliary rails, as well as multi-cell battery packs. |
Pinout & Package
LP2986AIMM-3.3/NOPB is packaged in an 8-pin VSSOP (DGK) with body size 3.00 mm × 3.00 mm, optimized for space-constrained portable designs. Thermal performance is enhanced by low RθJA = 156.5°C/W (JEDEC High-K board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GROUND (Pin 1) | Power return reference | Primary ground connection; all internal circuits referenced here - must be low-impedance path to system ground plane. |
| FEEDBACK (Pin 2) | Regulation sense input | Tied internally to TAP for fixed 3.3 V mode; connects to external resistor divider for adjustable output - not used in this variant. |
| TAP (Pin 3) | Internal divider mid-point | Connected to FEEDBACK internally to enable fixed 3.3 V output; unused when external feedback is applied. |
| IN (Pin 4) | Unregulated input supply | Accepts 2.1–16 V input; requires ≥2.2 µF input capacitor placed within 0.5 inch for stability. |
| OUT (Pin 5) | Regulated output | Delivers 3.3 V at up to 200 mA; requires ≥4.7 µF ceramic output capacitor for guaranteed stability. |
| SENSE (Pin 6) | Remote output sensing | Tied to OUT for local regulation; enables remote-sense compensation for PCB trace IR drop in precision applications. |
| ERROR (Pin 7) | Open-collector fault indicator | Active-low output asserting when VOUT < 3.135 V; requires external pull-up to VOUT or another supply ≤16 V. |
| SHUTDOWN (Pin 8) | Enable control input | Active-high logic input (VH ≥1.4 V); pulling low disables output and reduces IQ to <1 µA - ideal for host MCU control. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 180 mV typical at 200 mA - enables regulation from inputs as low as 3.48 V, critical for Li-ion battery discharge curves. |
| High output accuracy | ±0.5% at 25°C, ±0.7% over −40°C to +125°C - eliminates need for post-regulation trimming in industrial and medical sensors. |
| Integrated ERROR flag | Detects >5% VOUT sag with open-collector output - replaces discrete supervisor ICs in compact power management subsystems. |
| Micropower shutdown | <1 µA quiescent current in shutdown - extends shelf life and runtime in battery-backed memory or real-time clocks. |
| Robust protection suite | Thermal shutdown + current limit (400 mA peak) - prevents damage during overload or short-circuit events without external circuitry. |
Applications
| Cellular Phone Power Management | Palmtop/Laptop I/O Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76333DBVR | CMOS-based, 150 mA max, 120 mV dropout @ 150 mA, 2.5 µA quiescent current (active) | Lacks integrated ERROR flag and remote sensing; lower max current limits use in higher-load scenarios | Preferred where ultra-low active IQ is prioritized over fault monitoring and 200 mA capability |
| MCP1703T-3302E/MB | CMOS, 250 mA max, 600 mV dropout @ 250 mA, 2 µA quiescent current (active), no ERROR flag | Higher dropout restricts use with low-VIN sources; no built-in supervision requires external monitoring | Suitable for cost-sensitive, non-critical 3.3 V rails where input headroom >600 mV is available |
Compared with TPS76333DBVR and MCP1703T-3302E/MB, LP2986AIMM-3.3/NOPB uniquely combines 200 mA capability, ultra-low dropout, integrated ERROR flag, and remote sensing - making it the only option among the three qualified for precision battery-powered systems requiring both high load current and system-level fault detection.

FAQ
What is the maximum input voltage rating for LP2986AIMM-3.3/NOPB?
The LP2986AIMM-3.3/NOPB has an absolute maximum input voltage rating of 16 V and a recommended operating range of 2.1 V to 16 V. Exceeding 16 V may cause permanent damage. For reliable operation, maintain VIN within the recommended range and observe derating guidelines in the thermal section of the datasheet.
Does LP2986AIMM-3.3/NOPB require external capacitors, and what values are recommended?
Yes, LP2986AIMM-3.3/NOPB requires an input capacitor ≥2.2 µF and an output capacitor ≥4.7 µF ceramic for guaranteed stability. TI specifies these minimums based on extensive characterization; using smaller values risks oscillation or poor transient response. Place the input capacitor within 0.5 inch of the IN pin and connect the output capacitor directly between OUT and GROUND.
How does the ERROR pin on LP2986AIMM-3.3/NOPB function, and what external components are needed?
The ERROR pin on LP2986AIMM-3.3/NOPB is an open-collector output that pulls low when VOUT drops >5% below 3.3 V (i.e., <3.135 V). It requires an external pull-up resistor to VOUT or another supply ≤16 V. TI recommends a 10–100 kΩ resistor; the pin can sink up to 300 µA. Leaving ERROR unconnected is acceptable if fault monitoring is not required.
Can LP2986AIMM-3.3/NOPB be used in adjustable-output configurations?
No - LP2986AIMM-3.3/NOPB is factory-configured for fixed 3.3 V output using internal resistive dividers. While the LP2986 family supports adjustable operation via external feedback, this specific variant (AIMM-3.3/NOPB) ties FEEDBACK to TAP and SENSE to OUT internally; altering those connections invalidates the 3.3 V accuracy guarantee and voids specifications.
What thermal considerations apply to LP2986AIMM-3.3/NOPB in VSSOP package?
LP2986AIMM-3.3/NOPB in VSSOP (DGK) has RθJA = 156.5°C/W on JEDEC High-K board. At 200 mA and 16 V input, worst-case power dissipation is ~2.6 W, requiring careful PCB layout: use generous copper pour on GROUND layer, minimize trace resistance, and avoid enclosing the device. Thermal shutdown activates at ~160°C junction temperature.
