Product details
Overview
LP5990TM-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, and 30μA quiescent current in active mode. It operates from 2.2V to 5.5V input and supports logic-controlled enable for ultra-low-power shutdown (10nA).
For engineers reviewing the LP5990TM-3.3/NOPB datasheet, LP5990TM-3.3/NOPB pinout, LP5990TM-3.3/NOPB application, or LP5990TM-3.3/NOPB equivalent, this page provides verified technical context, package mapping, real-world design meaning of key specs, and validated alternative options for portable power management in space-constrained systems.
Technical Context
The LP5990TM-3.3/NOPB employs a CMOS pass transistor architecture enabling low dropout and high PSRR (55 dB at 10 kHz), with internal thermal-overload and short-circuit protection. Its push-pull enable circuitry achieves 60 μs startup and 500 μs shutdown times.
Designed for stability with 0402 1.0 µF ceramic capacitors on both input and output, it requires no external compensation and maintains regulation under no-load conditions. The device uses a 4-bump DSBGA package (0.4 mm pitch, 866 µm × 917 µm) with lead-free SNAGCU ball finish and MSL Level-1 rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1% over −40°C to +125°C junction temperature - ensures stable rail for MCU I/O or RF front-end biasing. |
| Max Output Current | 200mA continuous - sufficient for powering single-core microcontrollers or low-power sensors without thermal derating on JEDEC board. |
| Dropout Voltage | 160mV at 200mA load - enables operation from 3.46V input, critical for Li-ion battery discharge tail-end support. |
| Quiescent Current | 30μA enabled / 10nA disabled - extends battery life in always-on wearable or IoT endpoint applications. |
| Output Noise | 60 μVRMS (10 Hz–100 kHz) - low enough for noise-sensitive analog circuits like ADC references or RF synthesizers. |
| PSRR | 55 dB at 10 kHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Enable Threshold | VIL ≤ 0.35V, VIH ≥ 1.0V - compatible with 1.8V/3.3V GPIO without level-shifting in mixed-voltage systems. |
Pinout & Package
LP5990TM-3.3/NOPB uses a 4-bump DSBGA package (YFQ0004CEA), 0.4 mm pitch, 866 µm × 917 µm footprint, lead-free SNAGCU balls, MSL Level-1, and JEDEC-compliant thermal resistance (θJA = 100.6°C/W on JEDEC board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input voltage supply | Accepts 2.2V–5.5V; requires 1.0 µF ceramic capacitor within 1 cm to minimize input inductance and ensure stability. |
| VOUT | Regulated output | Delivers fixed 3.3V; must connect 1.0 µF X7R/X5R ceramic capacitor (5–500 mΩ ESR) directly to clean ground. |
| VEN | Logic-controlled enable | Active-high input; pulls regulator into 10nA shutdown when ≤0.35V; includes internal 3 MΩ pull-down resistor. |
| GND | Power ground reference | Common return path for VIN, VOUT, and VEN; must be low-impedance analog ground plane to avoid noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Stable with 0402 1.0 µF ceramics | Enables total solution size < 2.5 mm² - ideal for ultra-thin smartphones and hearables where board area is premium. |
| 60 μs startup time | Allows rapid wake-up from deep sleep in battery-powered sensors without compromising system responsiveness. |
| Thermal-overload protection | Shuts down at 160°C junction temperature with 20°C hysteresis - prevents permanent damage during transient overloads or poor PCB heatsinking. |
| Low-noise 60 μVRMS output | Eliminates need for post-regulator LC filtering in precision analog signal chains, reducing BOM count and layout complexity. |
| PSRR > 55 dB at 10 kHz | Mitigates ripple from buck converter switching frequencies, enabling clean 3.3V supply for RF transceivers without dedicated LDO sequencing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, low-IQ LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F33PDBVR | 300mA output, 25μA IQ, 120mV dropout at 300mA, same 4-bump DSBGA (0.4mm pitch) | Higher current capability but slightly lower PSRR (45 dB @ 10 kHz) and higher noise (75 μVRMS) | Choose for designs needing >200mA margin or tighter dropout, accepting trade-off in noise performance. |
| MCP1700T-3302E/TT | 250mA output, 1.6μA IQ (typ), 600mV dropout at 250mA, SOT-23-5 package | Ultra-low IQ but significantly higher dropout and larger footprint; no enable pin integrated | Choose only for extreme battery-life-critical applications where 200mA load and fast enable are not required. |
Compared with LP5990TM-3.3/NOPB, TPL720F33PDBVR offers higher current headroom in identical package size but sacrifices noise and PSRR; MCP1700T-3302E/TT delivers ultra-low IQ but requires larger board area and cannot support dynamic enable control or low-dropout operation near battery end-of-life.

FAQ
What is the maximum input voltage rating for LP5990TM-3.3/NOPB?
The absolute maximum input voltage (VIN) for LP5990TM-3.3/NOPB is 6.0V, but the recommended operating range is 2.2V to 5.5V per the datasheet. Exceeding 5.5V may trigger internal protection or cause reliability degradation. The device is optimized for single-cell Li-ion (4.2V max) and multi-cell alkaline/NiMH inputs, and its 160mV dropout ensures full 3.3V output even as input drops to 3.46V.
Does LP5990TM-3.3/NOPB require external compensation components?
No, LP5990TM-3.3/NOPB is internally compensated and stable with only 1.0 µF ceramic capacitors on both input and output. The datasheet explicitly states stability with 0402-case 1.0 µF X7R/X5R ceramics (5–500 mΩ ESR), eliminating need for external resistors or capacitors. This simplifies layout and reduces BOM count - a key advantage over older LDO architectures requiring 10 µF tantalum or aluminum electrolytic capacitors.
What is the thermal shutdown behavior of LP5990TM-3.3/NOPB?
LP5990TM-3.3/NOPB activates thermal shutdown at 160°C junction temperature and includes 20°C hysteresis, meaning it resumes normal operation only after junction temperature falls below 140°C. This protects against permanent damage during sustained overload or inadequate PCB copper pour. The device's θJA of 100.6°C/W on JEDEC board means ~125°C rise at 200mA with 1V dropout (200mW dissipation), so thermal shutdown typically engages only under fault conditions or extreme ambient temperatures.
Can LP5990TM-3.3/NOPB operate without any load connected?
Yes, LP5990TM-3.3/NOPB remains stable and in regulation with zero load current - confirmed in the "NO-LOAD STABILITY" section of the datasheet. This eliminates need for dummy loads in standby modes and supports applications like always-on real-time clocks or wake-up controllers where output must remain valid even when downstream circuitry is powered off.
Is LP5990TM-3.3/NOPB RoHS compliant and lead-free?
Yes, LP5990TM-3.3/NOPB is RoHS compliant and features lead-free SNAGCU (tin-silver-copper) ball finish on its DSBGA package. Per TI's packaging documentation, it carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified for standard Pb-free reflow profiles up to 260°C peak. The "/NOPB" suffix explicitly denotes lead-free packaging per TI's part numbering convention.
