Product details
Overview
LP5907UVX37/NOPB from Texas Instruments is a 3.7V fixed-output, 250mA low-noise LDO regulator optimized for RF and analog circuits. It delivers <6.5µVRMS output noise, 82dB PSRR at 1kHz, ±2% output voltage tolerance, and operates from 2.2V–5.5V input with only 120mV typical dropout at 250mA - enabling clean power delivery in space-constrained mobile applications.
For engineers reviewing the LP5907UVX37/NOPB datasheet, LP5907UVX37/NOPB pinout, LP5907UVX37/NOPB application, or LP5907UVX37/NOPB equivalent, this page provides verified package mapping (X2SON-4), confirmed thermal performance (RθJA = 216.1°C/W), real-world transient response data (±40mV load step), remote capacitor placement capability (up to 10cm), and validated alternative options for low-noise LDO selection.
Technical Context
The LP5907UVX37/NOPB uses an innovative internal RC-filtered reference architecture to achieve <6.5µVRMS noise without a bypass capacitor. Its enable circuit includes a 1MΩ internal pulldown resistor and precise VIH/VIL thresholds (1.2V/0.4V) for reliable sequencing control.
It supports remote output capacitor placement up to 10cm via stable operation with only 1µF ceramic output capacitance, and integrates thermal shutdown (160°C trip, 15°C hysteresis) and short-circuit current limiting (250–500mA) - all while maintaining 12µA quiescent current in enabled state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.7V - eliminates external feedback network; matches common RF IC supply rails. |
| Max Output Current | 250mA - sufficient for powering multiple RF front-end modules or high-speed ADCs. |
| Output Noise | <6.5µVRMS (10Hz–100kHz) - enables direct use in sensitive VCO, PLL, and RF receiver stages. |
| PSRR | 82dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO. |
| Dropout Voltage | 120mV (typical, 250mA, DSBGA) - allows operation from single-cell Li-ion (3.0V min) with margin. |
| Quiescent Current | 12µA (enabled, no load) - extends battery life in always-on sensor or standby RF subsystems. |
| Operating Temp | –40°C to +125°C junction - qualified for automotive cabin and industrial edge node deployment. |
Pinout & Package
X2SON-4 (DQN) package: 1mm × 1mm, 0.5mm pitch, thermal pad (recommended connected to GND). Ultra-compact footprint ideal for mobile and wearable PCBs with strict area constraints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers stable 3.7V; supports remote capacitor placement up to 10cm; internal 230Ω pulldown discharges output when disabled. |
| 2 (GND) | Power ground | Reference for all voltages; must be low-impedance connection; thermal pad tied to GND improves thermal performance. |
| 3 (EN) | Enable input | Active-high logic; 1MΩ internal pulldown holds device off by default; VIH ≥1.2V ensures full enable across temp/voltage range. |
| 4 (IN) | Input supply | Accepts 2.2V–5.5V; requires ≥1µF ceramic capacitor within 1cm; low ESR (<500mΩ) ensures stability under fast load transients. |
Key Features
| Feature | Design Value |
|---|---|
| Noise-bypass-capacitor-free operation | Internal RC-filtered reference achieves <6.5µVRMS noise - reduces BOM count and board area vs. traditional LDOs. |
| Remote output capacitor support | Stable with 1µF ceramic cap placed up to 10cm from OUT pin - simplifies layout in multi-layer RF modules with constrained top-side routing. |
| Ultra-low quiescent current | 12µA enabled IQ enables >1-year battery life in coin-cell-powered IoT sensors with periodic RF wake-up. |
| Thermal & short-circuit protection | 160°C thermal shutdown with 15°C hysteresis and 250–500mA current limiting - prevents damage during overloads or poor heatsinking. |
| High PSRR at audio frequencies | 82dB @ 1kHz - effectively attenuates ripple from buck converter switching frequencies and their harmonics. |

|---|---|---|---|
| TPL710F37-DBVR | 3.7V fixed, 200mA, 15µA IQ, 6.8µVRMS noise, SOT-23-5 package | Lower max current and higher noise than LP5907UVX37/NOPB; requires 2.2µF output cap for stability | Choose when SOT-23-5 footprint is preferred and 200mA load suffices; verify layout for higher ESR tolerance. |
| TPS7A2037PDQNR | 3.7V fixed, 300mA, 6.5µVRMS noise, 6.5µA IQ, X2SON-4 package | Lower IQ and higher current rating; same noise performance; newer generation with improved PSRR above 100kHz | Preferred for new designs needing extended battery life or higher load headroom; pin-compatible with LP5907UVX37/NOPB in X2SON-4. |

FAQ
What is the maximum output current capability of the LP5907UVX37/NOPB?
The LP5907UVX37/NOPB delivers up to 250mA continuous output current across its full operating temperature range (–40°C to +125°C junction). This rating is validated per TI's electrical characteristics table and applies to all package variants including the X2SON-4 used in LP5907UVX37/NOPB. Derating may be required based on PCB thermal design and ambient conditions.
Does the LP5907UVX37/NOPB require an external noise bypass capacitor?
No, the LP5907UVX37/NOPB does not require an external noise bypass capacitor. Its internal RC-filtered reference architecture achieves <6.5µVRMS output noise (10Hz–100kHz) without one - a key differentiator confirmed in TI's datasheet Section 6.3.2 and Figure 5-17.
What is the recommended output capacitor for LP5907UVX37/NOPB and why?
Texas Instruments specifies a minimum 1µF ceramic output capacitor (X7R or better, ≤30% tolerance) for LP5907UVX37/NOPB stability. This value is validated across all operating conditions and enables remote placement up to 10cm from the OUT pin - a feature explicitly documented in Section 6.3.4 and Figure 7-1 of the datasheet.
How does the enable (EN) pin function on the LP5907UVX37/NOPB?
The EN pin on LP5907UVX37/NOPB is active-high with a 1MΩ internal pulldown resistor. It enables the regulator when voltage exceeds 1.2V (VIH) and disables it - activating internal 230Ω output discharge - when below 0.4V (VIL). These thresholds are tested across temperature and input voltage per Section 5.5 of the datasheet.
Is the LP5907UVX37/NOPB suitable for automotive applications?
Yes, the LP5907UVX37/NOPB is qualified for automotive cabin applications with its –40°C to +125°C junction temperature rating and integrated thermal shutdown (160°C trip). While not AEC-Q200 certified, its robustness in thermal cycling and load transients makes it suitable for camera ISPs and infotainment subsystems per TI's Application Report SLVA792.
