Product details
Overview
LP5990TMX-3.3/NOPB from Texas Instruments is a micropower 200mA CMOS low-dropout voltage regulator delivering a fixed 3.3V output with ±1% accuracy over −40°C to +125°C, 160mV dropout at 200mA load, 30μA quiescent current (enabled), and stable operation with 1.0µF 0402 ceramic capacitors - deployed in space-constrained portable power rails for cellular phones and handheld information appliances.
For engineers reviewing the LP5990TMX-3.3/NOPB datasheet, LP5990TMX-3.3/NOPB pinout, LP5990TMX-3.3/NOPB application, or LP5990TMX-3.3/NOPB equivalent, this page delivers verified package mapping (4-bump DSBGA, YFQ0004CEA), validated thermal performance (θJA = 100.6°C/W on JEDEC board), confirmed enable control thresholds (VEN ≤0.35V disables, ≥1.0V enables), and real-world noise specification (60μVRMS at 1.8V output).
Technical Context
The LP5990TMX-3.3/NOPB employs a CMOS pass element architecture enabling ultra-low quiescent current (30μA active, 10nA shutdown) and fast transient response (60μs startup, 500μs shutdown). Its internal push-pull enable driver ensures rapid state transitions without external pull-up components.
Designed for stability with minimal external capacitance, it operates across 2.2V–5.5V input range while maintaining regulation under no-load conditions and supporting 0–200mA output current. PSRR of 55dB at 10kHz and 60μVRMS output noise reflect its suitability for noise-sensitive analog and RF subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1% over −40°C to +125°C junction temperature - ensures stable core/peripheral rail in battery-powered systems. |
| Max Output Current | 200mA continuous - sufficient for powering microcontrollers, sensors, and RF transceivers in compact portable devices. |
| Dropout Voltage | 160mV at 200mA load - enables regulation from 3.46V input, critical for extending battery life in single-cell Li-ion applications. |
| Quiescent Current | 30μA (enabled), 10nA (disabled) - minimizes standby power loss in always-on or duty-cycled IoT endpoints. |
| Output Noise | 60μVRMS (10Hz–100kHz, VOUT=1.8V) - low enough for powering ADC references and PLL VCO supplies without added filtering. |
| PSRR | 55dB at 10kHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Capacitor Requirement | Stable with 1.0µF X7R/X5R 0402 ceramic (ESR 5–500mΩ) - reduces PCB area to <2.5mm² total solution size. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A2 | VEN | Logic-controlled enable input; asserts shutdown when ≤0.35V, activates regulator when ≥1.0V - eliminates need for external pull-up resistor. |
| A1 | GND | Common ground reference for all internal circuitry and external capacitors - must connect to low-impedance analog ground plane. |
| B1 | VOUT | Regulated 3.3V output; requires 1.0µF ceramic capacitor placed within 1cm - defines power integrity for downstream loads. |
| B2 | VIN | Input supply (2.2–5.5V); requires 1.0µF ceramic capacitor placed within 1cm - filters high-frequency noise before regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower Operation | 30μA IQ enabled / 10nA IQ disabled - extends battery runtime in wearable and remote sensor nodes beyond 1 year. |
| Ultra-Small Solution Size | <2.5mm² total footprint using 0402 1.0µF ceramics - enables integration into ultra-thin mobile and medical patch devices. |
| Fast Transient Response | 60μs startup time, 500μs shutdown time - supports dynamic power sequencing in multi-rail SoC systems. |
| Robust Protection | Thermal overload and short-circuit current limiting (600mA typical) - prevents damage during fault conditions without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, micropower LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F33DRVR | 300mA output, 25μA IQ, 120mV dropout at 300mA, same 4-bump DSBGA (0.4mm pitch) | Higher current capability suits future-proofing for upgraded SoCs; slightly lower dropout improves margin at end-of-battery-life. | Select if system load may exceed 200mA or requires tighter dropout; pinout identical but thermal derating differs due to higher max current. |
| MCP1700T-3302E/TT | 250mA output, 1.8μA IQ (typ), 600mV dropout at 250mA, SOT-23-5 package | Ultra-low IQ ideal for multi-year battery life; larger dropout limits use with <3.9V inputs; through-hole-compatible footprint. | Choose for extreme energy harvesting or coin-cell applications where 200mA is sufficient and board space allows SOT-23-5. |
Compared with TPL720F33DRVR, LP5990TMX-3.3/NOPB offers lower noise (60 vs. 85μVRMS) and better PSRR (55 vs. 45dB), making it preferable for analog-signal integrity; versus MCP1700T-3302E/TT, it trades 28× higher IQ for 3.7× lower dropout and 0.5mm² smaller footprint - optimal for space-constrained, moderate-duty-cycle designs.

FAQ
What is the maximum input voltage rating for LP5990TMX-3.3/NOPB?
The absolute maximum input voltage (VIN) for LP5990TMX-3.3/NOPB is 6.0V. However, the recommended operating range is 2.2V to 5.5V per the datasheet. Exceeding 5.5V risks violating operating specifications and may trigger internal protection mechanisms or cause permanent damage. Always maintain VIN within 2.2V–5.5V for reliable 3.3V regulation in LP5990TMX-3.3/NOPB applications.
Does LP5990TMX-3.3/NOPB require an external pull-up resistor on the VEN pin?
No, LP5990TMX-3.3/NOPB does not require an external pull-up resistor on the VEN pin. The device integrates a 3MΩ internal resistor from VEN to GND, allowing direct connection to a logic controller GPIO without additional components. When the controlling signal is high (≥1.0V), the regulator enables; when low (≤0.35V), it enters shutdown consuming only 10nA - simplifying design and reducing BOM count for LP5990TMX-3.3/NOPB implementations.
Can LP5990TMX-3.3/NOPB operate stably with a 0.47µF output capacitor?
No, LP5990TMX-3.3/NOPB is not guaranteed stable with a 0.47µF output capacitor. The datasheet specifies a minimum output capacitance of 0.3µF, but mandates 1.0µF for guaranteed stability across temperature, voltage, and aging - especially with 0402 X7R/X5R ceramics. Using 0.47µF risks oscillation or poor transient response due to insufficient phase margin; LP5990TMX-3.3/NOPB must use ≥1.0µF ceramic with ESR between 5–500mΩ for production compliance.
What is the thermal resistance (θJA) of LP5990TMX-3.3/NOPB on a standard JEDEC board?
The junction-to-ambient thermal resistance (θJA) of LP5990TMX-3.3/NOPB is 100.6°C/W when mounted on a JEDEC-standard board per JESD51-7. This value assumes proper PCB layout with thermal vias and copper pour under the DSBGA package. In real-world layouts like a 4-layer cellphone board, θJA rises to 174.8°C/W - so thermal design for LP5990TMX-3.3/NOPB must account for actual board construction to avoid exceeding 125°C junction temperature at 200mA load.
Is LP5990TMX-3.3/NOPB compatible with lead-free reflow soldering processes?
Yes, LP5990TMX-3.3/NOPB is fully compatible with lead-free reflow soldering. It carries an MSL Level-1 rating (unlimited floor life) and is qualified for peak reflow temperatures up to 260°C per JEDEC J-STD-020. The package uses SNAGCU (tin-silver-copper) ball finish, and TI confirms compatibility with standard Pb-free assembly profiles - ensuring robust interconnect reliability for LP5990TMX-3.3/NOPB in high-volume manufacturing environments.
