Product details
Overview
LP5990TM-3.0/NOPB from Texas Instruments is a micropower 200mA CMOS low-dropout voltage regulator delivering a fixed 3.0V output with ±1% accuracy over −40°C to +125°C, 160mV dropout at 200mA, 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-3.0/NOPB datasheet, LP5990TM-3.0/NOPB pinout, LP5990TM-3.0/NOPB application, or LP5990TM-3.0/NOPB equivalent, this device is selected for space-constrained portable systems requiring stable 3.0V rail generation with minimal external components-especially where 0402 1.0µF ceramic capacitors and DSBGA footprint are critical.
Technical Context
The LP5990TM-3.0/NOPB uses a CMOS pass transistor architecture enabling low dropout and low noise operation. Its internal push-pull enable driver achieves 60μs startup and 500μs shutdown, while thermal-overload and short-circuit protection ensure robustness in battery-powered environments.
Stability is guaranteed with 1.0µF ±30% X7R/X5R ceramic capacitors on both input and output-no ESR constraints required beyond 5–500mΩ-and the regulator remains functional with zero load current, supporting always-on subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% over −40°C to +125°C junction temperature-ensures precise biasing for 3.0V I/O or core rails without external feedback. |
| Max Output Current | 200mA continuous-supports moderate-power microcontrollers, sensors, or RF front-ends in handheld devices. |
| Dropout Voltage | 160mV at 200mA load-enables regulation from 3.16V input, extending battery runtime in single-cell Li-ion or dual-cell alkaline systems. |
| Quiescent Current | 30μA enabled / 10nA disabled-minimizes standby power loss in sleep-mode applications like cellular modems or wearables. |
| Noise Performance | 60μVRMS (10Hz–100kHz, VOUT=3.0V)-low enough for noise-sensitive analog circuits such as ADC references or audio codecs. |
| PSRR | 55dB at 10kHz-effectively suppresses switching noise from DC/DC converters sharing the same input source. |
| Capacitor Support | Stable with 0402 1.0µF ceramic (X7R/X5R, 5–500mΩ ESR)-reduces total solution area to <2.5mm² and eliminates need for larger 0603 or tantalum parts. |
Pinout & Package
LP5990TM-3.0/NOPB is housed in a 4-bump DSBGA package (YFQ0004CEA), 0.4mm pitch, 866µm × 917µm footprint, lead-free, moisture sensitivity level 1 (260°C peak reflow). The package is light-sensitive and requires shielding from direct IR/red illumination during operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input voltage supply | Accepts 2.2V–5.5V; requires local 1.0µF ceramic capacitor within 1cm of pin to minimize input inductance and ensure stability. |
| VOUT | Regulated output | Delivers fixed 3.0V; must connect 1.0µF ceramic capacitor directly to ground with low-inductance layout to maintain 60μVRMS noise and transient response. |
| VEN | Logic-enable input | Active-high control: ≥1.0V enables regulation; ≤0.35V disables output and reduces IQ to 10nA; internal 3MΩ pull-down aids default-off behavior. |
| GND | Power ground reference | Common return for VIN, VOUT, and VEN; must be connected to clean analog ground plane-shared digital ground increases noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 30μA IQ (enabled) and 10nA IQ (disabled) extend battery life in intermittent-use devices like remote controls or IoT endpoints. |
| Ultra-small solution size | Stable with 0402 1.0µF ceramics-enables total PCB area <2.5mm², ideal for thin smartphones, TWS earbuds, and medical patches. |
| Fast transient response | ±50mV load step (1mA ↔ 200mA in 1μs) and 4mV line step (600mV ΔVIN) ensure stable power delivery to burst-mode processors. |
| Integrated protection | Thermal shutdown (160°C trip, 20°C hysteresis) and short-circuit current limit (600mA typical) prevent damage during fault conditions. |
| High PSRR at key frequencies | 55dB rejection at 10kHz suppresses ripple from buck converter switching edges, reducing need for post-regulation filtering. |
Applications
| Cellular Phone Power Management | Handheld Medical Sensor Module |

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 |
|---|---|---|---|
| TPL720F30DRVR | 300mA output, 250mV dropout at 300mA, 25μA IQ, same 4-bump DSBGA (0.4mm pitch), but requires minimum 2.2µF output capacitance. | Better suited for higher-current loads; less optimal for strict 0402/1.0µF space constraints. | Select if >200mA peak load is needed and board area allows larger capacitor. |
| MCP1700T-3002E/MB | 250mA output, 600mV dropout at 250mA, 1.6μA IQ, SOT-23-5 package, 2% output tolerance, no enable pin. | Larger footprint, higher dropout limits low-VIN operation; ultra-low IQ benefits long-term storage but lacks dynamic control. | Choose when lowest possible quiescent current dominates and enable functionality is unnecessary. |
Compared with TPL720F30DRVR and MCP1700T-3002E/MB, LP5990TM-3.0/NOPB uniquely balances 200mA capability, 160mV dropout, 30μA IQ, and 0402 capacitor support in a 0.9mm² DSBGA-making it optimal for compact, battery-sensitive designs where all three parameters are simultaneously constrained.

FAQ
What is the maximum input voltage rating for LP5990TM-3.0/NOPB?
The absolute maximum input voltage (VIN) for LP5990TM-3.0/NOPB is 6.0V. However, the recommended operating range is 2.2V to 5.5V per the datasheet's Operating Ratings. Exceeding 5.5V may trigger internal protection or cause reliability degradation, even if below the 6.0V absolute limit. Always maintain VIN within 2.2V–5.5V for guaranteed specification compliance and long-term reliability.
Does LP5990TM-3.0/NOPB require an external resistor on the VEN pin?
No, LP5990TM-3.0/NOPB does not require an external resistor on the VEN pin. It includes an internal 3MΩ pull-down resistor to ground, ensuring reliable disable state when left floating or driven low. An external resistor is only needed if precise threshold control or noise immunity is required beyond the specified VIL ≤0.35V and VIH ≥1.0V.
Can LP5990TM-3.0/NOPB operate without any load connected to VOUT?
Yes, LP5990TM-3.0/NOPB remains stable and in regulation with no external load (0mA output current). This no-load stability is explicitly confirmed in the datasheet's "NO-LOAD STABILITY" section and is enabled by its CMOS architecture and compensation design-making it suitable for always-on monitoring circuits or standby power domains.
What capacitor dielectric types are recommended for LP5990TM-3.0/NOPB?
X7R and X5R ceramic dielectrics are recommended for both input and output capacitors in LP5990TM-3.0/NOPB applications. These offer sufficient capacitance retention over temperature and DC bias. Y5V and Z5U are discouraged due to severe capacitance loss (>50%) at elevated temperatures or bias voltages, potentially violating the 0.3µF minimum requirement.
Is LP5990TM-3.0/NOPB compatible with automated optical inspection (AOI) after assembly?
LP5990TM-3.0/NOPB's DSBGA package is compatible with standard AOI systems, but its light sensitivity-particularly to red/IR wavelengths-requires that inspection lighting avoid halogen or high-intensity incandescent sources. Fluorescent or LED-based AOI systems operating outside 650–1100nm are safe; verify spectral output with your AOI vendor to prevent temporary parametric shifts during inspection.
