Product details
Overview
LP5907SNX-2.7/NOPB from Texas Instruments is a 250mA, low-noise, low-IQ linear regulator delivering fixed 2.7V output with ±2% tolerance, 12μA quiescent current (enabled), <6.5µVRMS output noise, and 82dB PSRR at 1kHz - designed for RF and analog power rails in space-constrained portable electronics.
For engineers reviewing the LP5907SNX-2.7/NOPB datasheet, LP5907SNX-2.7/NOPB pinout, LP5907SNX-2.7/NOPB application, or LP5907SNX-2.7/NOPB equivalent, this page provides verified package mapping (X2SON-4), validated pin functions, confirmed thermal performance (RθJA = 216.1°C/W), real-world remote capacitor placement capability (up to 10cm), and two technically documented alternative LDOs for noise-sensitive 2.7V rail design.
Technical Context
The LP5907SNX-2.7/NOPB employs a proprietary low-noise reference architecture with integrated first-order RC filtering (–3dB at ~0.1Hz) to achieve <6.5µVRMS noise without external bypass capacitors. Its enable logic includes a 1MΩ internal pulldown and VIH/VIL thresholds (1.2V/0.4V) referenced to VIN.
It operates across –40°C to 125°C junction temperature with thermal shutdown at 160°C (15°C hysteresis) and supports stable regulation using only 1µF ceramic input and output capacitors - including remote placement of the output capacitor up to 10cm from the device due to inherent loop stability and low ESR sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 2.7V ±2% - ensures precise biasing for 2.7V-tolerant RF ICs and analog sensors without external feedback components. |
| Max output current | 250mA - sufficient to power baseband processors, RF transceivers, or multiple low-power analog blocks from a single rail. |
| Quiescent current | 12μA (enabled) - enables multi-week battery life in always-on sensor nodes or standby circuits without compromising regulation. |
| Output noise | <6.5µVRMS (10Hz–100kHz) - eliminates need for noise-bypass caps, reducing BOM count and PCB area in sensitive ADC/DAC or VCO supply paths. |
| PSRR | 82dB at 1kHz - suppresses switching noise from adjacent DC/DC converters, critical for clean power in mixed-signal SoCs. |
| Dropout voltage | 120mV at 250mA (DSBGA), 250mV at 250mA (SOT-23/X2SON) - enables high-efficiency operation from 3.0V input while maintaining 2.7V output under full load. |
| Input voltage range | 2.2V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V), Li-polymer, or regulated 3.3V/5V system rails. |
Pinout & Package
X2SON-4 (DQN) package: 1mm × 1mm, 0.5mm pitch, thermal pad (optional GND connection). Compact footprint ideal for ultra-thin mobile and wearable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers stable 2.7V; supports remote capacitor placement up to 10cm; internal 230Ω pulldown discharges output when disabled. |
| 2 (GND) | Power ground | Common return path for input, output, and enable; thermal pad (pin 5) may be connected to GND for improved thermal performance. |
| 3 (EN) | Enable control | Active-high logic; internal 1MΩ pulldown holds regulator off by default; VIH = 1.2V, VIL = 0.4V - compatible with 1.8V/3.3V GPIOs. |
| 4 (IN) | Input supply | Accepts 2.2–5.5V; requires ≥1µF ceramic cap within 1cm; low-ESR (<500mΩ) ensures transient stability during load steps. |
Key Features
| Feature | Design Value |
|---|---|
| Noise-bypass-capacitor-free operation | Integrated RC-filtered reference reduces output noise to <6.5µVRMS, eliminating one passive component and associated layout risk. |
| Remote output capacitor support | Stable with 1µF ceramic cap placed up to 10cm from OUT pin - enables flexible PCB routing for decoupling near noise-sensitive loads. |
| Ultra-low quiescent current | 12μA enabled / 0.2–1μA disabled - extends battery runtime in IoT endpoints and wearables without sacrificing startup speed (80–150µs turn-on). |
| Thermal overload protection | Shuts down at 160°C with 15°C hysteresis - prevents permanent damage during sustained overloads or poor heatsinking in sealed enclosures. |
| 1µF input/output stability | Guaranteed stable with minimal 1µF X7R ceramics on both sides - reduces solution size and cost versus legacy LDOs requiring ≥10µF caps. |

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 |
|---|---|---|---|
| TPL720F27 | 200mA max output, 8μA IQ, 4.5µVRMS noise, same 2.7V fixed output | Lower current capacity; better noise performance but reduced load headroom | Select when <200mA load and absolute minimum noise (<4.5µVRMS) are prioritized over margin. |

FAQ
What is the maximum output current supported by the LP5907SNX-2.7/NOPB?
The LP5907SNX-2.7/NOPB delivers up to 250mA of continuous output current while maintaining regulation and specified noise/PSRR performance. This is confirmed in Section 5.5 of the official datasheet under "Maximum output current" and validated across all package variants including the X2SON-4 used in LP5907SNX-2.7/NOPB. Exceeding 250mA may trigger current limiting or thermal shutdown.
Does the LP5907SNX-2.7/NOPB require an external noise bypass capacitor?
No, the LP5907SNX-2.7/NOPB does not require an external noise bypass capacitor. Its internal low-noise reference includes a first-order RC filter (–3dB at ~0.1Hz), enabling <6.5µVRMS output noise with only a 1µF ceramic output capacitor. This is explicitly stated in the Features list and Section 6.3.2 of the datasheet, and confirmed across all fixed-output variants including LP5907SNX-2.7/NOPB.
What is the recommended output capacitor placement distance for the LP5907SNX-2.7/NOPB?
The LP5907SNX-2.7/NOPB supports remote output capacitor placement up to 10cm from the OUT pin, as verified in Section 6.3.4 and Figure 7-1 of the datasheet. This capability stems from its inherent loop stability with 1µF ceramic capacitors and low sensitivity to trace inductance - enabling localized decoupling at noise-sensitive loads like RF ICs or image sensors without compromising regulation.
What are the enable logic thresholds for the LP5907SNX-2.7/NOPB?
The LP5907SNX-2.7/NOPB has VIH = 1.2V (minimum) and VIL = 0.4V (maximum) for reliable enable/disable operation, as specified in Section 5.5 Electrical Characteristics. These thresholds are referenced to VIN and remain stable across the full input range (2.2V–5.5V), ensuring compatibility with 1.8V and 3.3V GPIOs. An internal 1MΩ pulldown resistor guarantees default-off behavior.
Is the LP5907SNX-2.7/NOPB suitable for automotive applications?
The LP5907SNX-2.7/NOPB is rated for –40°C to 125°C junction temperature and includes thermal shutdown (160°C) and short-circuit protection, but it is not AEC-Q200 qualified or marketed by Texas Instruments for automotive use. Its qualification scope covers industrial, portable, and consumer applications per the official product folder and datasheet scope - therefore LP5907SNX-2.7/NOPB should not be deployed in safety-critical or automotive-grade systems without additional validation.
