Product details
Overview
LP5907UVX-3.1/NOPB from Texas Instruments is a fixed 3.1V, 250mA low-noise LDO regulator designed for RF and analog power rails. It delivers <6.5µVRMS output noise, 82dB PSRR at 1kHz, 12µA quiescent current, and operates from 2.2V–5.5V input with only 120mV typical dropout - enabling clean, efficient biasing of sensitive ADCs, RF transceivers, and PLLs in space-constrained portable devices.
For engineers reviewing the LP5907UVX-3.1/NOPB datasheet, LP5907UVX-3.1/NOPB pinout, LP5907UVX-3.1/NOPB application, or LP5907UVX-3.1/NOPB equivalent, this page provides verified package mapping (YCR DSBGA-4), confirmed pin functions (IN/OUT/EN/GND), real-world transient response data, remote capacitor placement capability, and validated alternatives for noise-critical LDO selection.
Technical Context
The LP5907UVX-3.1/NOPB uses a proprietary low-noise bandgap reference with integrated RC filtering (–3dB at ~0.1Hz) to achieve <6.5µVRMS noise without external bypass capacitors. Its internal 230Ω pulldown resistor enables automatic output discharge during shutdown, supporting controlled power sequencing in multi-rail systems.
It supports remote output capacitor placement up to 10cm from the device while maintaining stability with only 1µF ceramic COUT, and features thermal shutdown activation at 160°C with 15°C hysteresis - critical for sustained operation in thermally dense smartphone and tablet PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.1V ±2% - ensures stable bias for 3.3V-tolerant analog ICs without external feedback network. |
| Max output current | 250mA - sufficient for powering RF front-end modules, high-speed ADCs, or multiple low-power sensors simultaneously. |
| Quiescent current | 12µA (enabled) - extends battery life in always-on sensor nodes and wearable standby modes. |
| Output noise | <6.5µVRMS (10Hz–100kHz) - eliminates need for noise-bypass cap, reducing BOM count and PCB area. |
| PSRR | 82dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding noisy system rails. |
| Dropout voltage | 120mV at 250mA (DSBGA) - enables operation from single-cell Li-ion (3.0V min) while maintaining regulation. |
| Input range | 2.2V to 5.5V - compatible with USB, Li-ion, and wide-input industrial supplies without pre-regulation. |
Pinout & Package
LP5907UVX-3.1/NOPB is packaged in a 0.685mm × 0.685mm, 4-ball DSBGA (YCR) with bottom-side solder balls. This ultra-compact wafer-level chip-scale package minimizes parasitic inductance and thermal resistance (RθJA = 189.4°C/W), supporting high-density mobile PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN | Input supply pin - requires ≥1µF ceramic capacitor placed ≤1cm from pin to ensure stability under load transients. |
| A2 | OUT | Regulated 3.1V output - supports remote capacitor placement up to 10cm; internal 230Ω pulldown discharges VOUT when disabled. |
| B1 | EN | Active-high enable - VIH ≥1.2V, VIL ≤0.4V; internal 1MΩ pulldown holds regulator off by default for safe power-up sequencing. |
| B2 | GND | Common ground reference - must be connected to low-impedance analog ground plane to preserve noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| Noise-bypass capacitor elimination | Integrated RC-filtered reference reduces output noise to <6.5µVRMS without external bypass cap - saves 0.5mm² PCB area and one BOM line. |
| Remote output capacitor support | Stable with 1µF ceramic COUT placed up to 10cm from device - enables flexible layout in stacked or flex-based mobile designs. |
| Ultra-low quiescent current | 12µA IQ at full 250mA load - maintains efficiency in battery-powered always-on applications like IoT edge sensors. |
| Fast transient response | ±40mV load transient deviation (1mA ↔ 250mA in 10µs) - prevents brownout in burst-mode RF transmission. |
| Thermal-safe shutdown | 160°C junction trip with 15°C hysteresis - protects against sustained overload without requiring external thermal monitoring. |
Applications
| Smartphone RF Front-End | Digital Still Camera Sensor Bias |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F33PDBVR | 3.3V output, 200mA max, 5µVRMS noise, 25µA IQ - lower noise but reduced current and higher IQ than LP5907UVX-3.1/NOPB. | Preferred for ultra-low-noise audio bias where 3.3V matches downstream logic; unsuitable for 250mA RF loads. | Select when noise floor is primary constraint and load current ≤200mA; verify 3.3V compatibility with target ICs. |
| TPS7A2031PDQNR | 3.1V output, 300mA max, 7µVRMS noise, 6.5µA IQ - higher current rating and lower IQ, but requires minimum 0.47µF COUT and lacks remote capacitor support. | Better for high-current, ultra-low-IQ applications like always-on MCU cores; not optimized for RF layout flexibility. | Choose when maximizing battery life at light loads is critical and PCB layout permits local capacitor placement. |
Compared with TPL720F33PDBVR and TPS7A2031PDQNR, LP5907UVX-3.1/NOPB uniquely balances 250mA drive, 6.5µVRMS noise, 12µA IQ, and 10cm remote capacitor capability - making it optimal for RF/analog co-location in constrained mobile form factors where all four parameters matter simultaneously.

FAQ
What is the maximum output current supported by the LP5907UVX-3.1/NOPB?
The LP5907UVX-3.1/NOPB delivers up to 250mA of continuous output current while maintaining regulation and specified noise/PSRR performance. This rating applies across the full operating temperature range (–40°C to 125°C) and is validated for the YCR DSBGA-4 package. Current limiting activates at ~250–500mA to protect the device during short-circuit conditions.
Does the LP5907UVX-3.1/NOPB require an external noise-bypass capacitor?
No, the LP5907UVX-3.1/NOPB does not require an external noise-bypass capacitor. Its internal low-pass RC filter on the reference voltage achieves <6.5µVRMS output noise (10Hz–100kHz) without additional components - a key differentiator confirmed in the official datasheet Section 6.3.2 and electrical characteristics table.
What is the recommended input and output capacitance for the LP5907UVX-3.1/NOPB?
The LP5907UVX-3.1/NOPB is stable with a minimum 1µF ceramic input capacitor (CIN) and 1µF ceramic output capacitor (COUT). The datasheet specifies 0.7µF as the absolute minimum for both, with X7R dielectric recommended. COUT may be increased up to 10µF for improved transient response, and can be placed up to 10cm from the device.
How does the enable (EN) pin function on the LP5907UVX-3.1/NOPB?
The EN pin on the LP5907UVX-3.1/NOPB is active-high with internal 1MΩ pulldown. It enables the regulator when voltage exceeds 1.2V (VIH) and disables it below 0.4V (VIL). During disable, an internal 230Ω pulldown resistor actively discharges the output, ensuring rapid VOUT decay - critical for power sequencing in multi-rail systems.
What package type is used for the LP5907UVX-3.1/NOPB and what are its key mechanical properties?
The LP5907UVX-3.1/NOPB uses the YCR package: a 4-ball, 0.685mm × 0.685mm DSBGA (Die Size Ball Grid Array). It features 0.35mm ball pitch, bottom-side solder connections, and a nominal height of 0.26mm - optimized for ultra-thin mobile PCBs and automated assembly with fine-pitch reflow profiles.
