Product details
Overview
LP2986IMMX-5.0 from Texas Instruments is a micropower, 200-mA ultra-low-dropout linear voltage regulator in an 8-pin VSSOP package, delivering fixed 5.0 V output with ±0.5% accuracy (A-grade), 180 mV typical dropout at 200 mA, and <1 µA quiescent current in shutdown - deployed in battery-powered portable electronics requiring precision, low-noise, and thermal robustness.
For engineers reviewing the LP2986IMMX-5.0 datasheet, LP2986IMMX-5.0 pinout, LP2986IMMX-5.0 application, or LP2986IMMX-5.0 equivalent, key selection considerations include its verified 5.0 V fixed output accuracy, integrated ERROR flag with 5% undervoltage detection, active-high SHUTDOWN control, ground current of 1 mA at full load, and compatibility with ceramic output capacitors ≥4.7 µF.
Technical Context
The LP2986IMMX-5.0 uses a vertically integrated PNP (VIP) bipolar process to achieve ultra-low dropout and high PSRR (65 dB at 1 kHz), with internal feedback reference fixed at 1.23 V and remote sensing capability via SENSE pin. Its error comparator monitors output regulation continuously and asserts open-collector ERROR when VOUT falls >5% below nominal.
It operates across −40°C to +125°C junction temperature, supports input voltages from 2.1 V to 16 V, and integrates overtemperature and short-circuit protection. The device enters sleep mode (<1 µA IQ) when SHUTDOWN is pulled low, with defined turn-on/turn-off thresholds (VH = 1.4 V, VL = 0.55 V) and minimum slew rate requirement (40 mV/µs) for reliable mode transitions.
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 MCU core or analog sensor supply without external trimming. |
| Dropout Voltage | 180 mV typical at 200 mA load - enables regulation from 5.18 V input, critical for single-cell Li-ion or multi-cell alkaline systems. |
| Quiescent Current | <1 µA in shutdown; 1 mA typical at 200 mA load - extends battery life in always-on portable devices. |
| Ground Pin Current | 1 mA at 200 mA output (not load-dependent) - simplifies power budgeting vs. traditional LDOs with rising GND current. |
| ERROR Flag Threshold | Asserts low when VOUT drops ≥5% below 5.0 V - provides deterministic system reset or fault logging without external supervisor IC. |
| PSRR | 65 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Output Noise | 160 µVRMS (300 Hz–50 kHz) - suitable for noise-sensitive analog circuits like ADC references or RF bias rails. |
Pinout & Package
LP2986IMMX-5.0 is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, with exposed pad for thermal enhancement. Pin functions are identical across SOIC, VSSOP, and WSON variants per TI's official pin configuration documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: GROUND | Reference node | Common return path for load, internal circuitry, and thermal pad connection - must be low-impedance to minimize output error. |
| 2: FEEDBACK | Voltage sense input | Connected internally to TAP for fixed 5.0 V operation; accepts external resistor divider for adjustable outputs - sets regulation point via 1.23 V reference. |
| 3: TAP | Internal divider mid-point | Output of internal resistive divider; tied to FEEDBACK to enable fixed-voltage mode - eliminates need for external components in 5.0 V applications. |
| 4: IN | Input supply | Accepts 2.1 V–16 V unregulated input; includes reverse-input protection diode - tolerates transient overvoltage and back-driving. |
| 5: OUT | Regulated output | Delivers up to 200 mA at 5.0 V; requires ≥4.7 µF ceramic capacitor for stability - low ESR support enables compact, high-reliability designs. |
| 6: SENSE | Remote output sensing | Tied to OUT for local regulation; enables Kelvin sensing to compensate for PCB trace IR drop in high-accuracy applications. |
| 7: ERROR | Open-collector fault flag | Active-low signal sinking ≤300 µA; requires external pull-up to VOUT or another rail - provides fail-safe monitoring without additional ICs. |
| 8: SHUTDOWN | Enable control | Active-high logic input; pulls low to disable output and reduce IQ to <1 µA - compatible with standard GPIOs and sequencer outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 180 mV at 200 mA enables operation from marginal input sources (e.g., aging batteries or post-DC/DC rails). |
| 0.5% output accuracy (A grade) | Guaranteed at 25°C and validated over full temperature range - eliminates calibration in precision analog subsystems. |
| Integrated ERROR flag | Detects ≥5% output sag with no external components - replaces discrete supervisor circuits in space-constrained designs. |
| Micropower shutdown | <1 µA quiescent current in disabled state - essential for IoT endpoints and wearables with multi-year battery requirements. |
| Thermal & current protection | Auto-shutdown on overtemperature or short-circuit - prevents damage during fault conditions without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70750DBVR | CMOS-based, 300 mA rated, 250 mV dropout at 300 mA, 25 µA quiescent current (active), no ERROR flag. | Lacks integrated undervoltage monitor; requires external supervisor for reset functionality. | Preferred where higher output current and lower active IQ are prioritized over fault detection. |
| TPS7A2050PDBVR | CMOS-based, 300 mA rated, 175 mV dropout at 300 mA, 6.5 µA quiescent current (active), no ERROR flag. | No built-in ERROR output; relies on host processor polling or external monitoring. | Better suited for low-noise, low-IQ applications without system-level fault signaling requirements. |
Compared with TLV70750DBVR and TPS7A2050PDBVR, the LP2986IMMX-5.0 trades higher active quiescent current for integrated diagnostic capability (ERROR flag), bipolar process stability under wide VIN, and guaranteed 0.5% accuracy - making it optimal for safety-aware or supervisor-free portable systems.

FAQ
What is the output voltage tolerance of the LP2986IMMX-5.0 over temperature?
The LP2986IMMX-5.0 delivers 5.0 V output with ±0.5% initial accuracy at 25°C (A grade). Over the full −40°C to +125°C junction temperature range, total output variation is ±0.8%, including line, load, and temperature effects - verified per TI's Electrical Characteristics table in SNVS137I Rev I.
Does the LP2986IMMX-5.0 require external components to operate in fixed 5.0 V mode?
No. The LP2986IMMX-5.0 achieves fixed 5.0 V output by connecting SENSE to OUT and FEEDBACK to TAP - both pins are internally configured for this function. No external resistors or capacitors beyond the mandatory 4.7 µF output capacitor are needed for basic operation.
How does the ERROR pin on the LP2986IMMX-5.0 function, and what external circuitry is required?
The ERROR pin is an open-collector output that goes low when VOUT drops ≥5% below 5.0 V. An external pull-up resistor (to VOUT or another supply ≤16 V) is mandatory; TI specifies it must sink ≤300 µA. If unused, the pin may be left floating per datasheet guidance.
What is the minimum input voltage required for the LP2986IMMX-5.0 to maintain regulation at 200 mA?
With a typical dropout voltage of 180 mV at 200 mA, the LP2986IMMX-5.0 maintains 5.0 V regulation down to VIN = 5.18 V. The absolute minimum operating input is 2.1 V, but regulation ceases below the dropout threshold - confirmed in Section 6.3 Recommended Operating Conditions.
Can the LP2986IMMX-5.0 be used with ceramic output capacitors, and what is the minimum value?
Yes - the LP2986IMMX-5.0 is stable with ceramic output capacitors ≥4.7 µF and low ESR. TI explicitly validates this in Section 8.2.2.2.2, noting that larger values improve transient response without compromising stability, unlike older LDO architectures requiring specific ESR ranges.
