Product details
Overview
LP5907UVE-3.2/NOPB from Texas Instruments is a 250mA, low-noise, low-IQ linear regulator delivering a fixed 3.2V output with ±2% tolerance, 120mV typical dropout at 250mA, <6.5µVRMS output noise, and 82dB PSRR at 1kHz - designed for RF and analog power rails in space-constrained portable devices.
For engineers reviewing the LP5907UVE-3.2/NOPB datasheet, LP5907UVE-3.2/NOPB pinout, LP5907UVE-3.2/NOPB application, or LP5907UVE-3.2/NOPB equivalent, this page provides verified package mapping (X2SON-4), confirmed pin functions (IN/OUT/EN/GND), thermal performance data (RθJA = 216.1°C/W), remote capacitor placement capability (≤10cm), and two validated alternative LDOs for noise-sensitive, low-IQ designs.
Technical Context
The LP5907UVE-3.2/NOPB employs a proprietary low-noise reference architecture with integrated RC filtering (–3dB at ~0.1Hz) to achieve <6.5µVRMS noise without an external bypass capacitor. Its enable circuit includes a 1MΩ internal pulldown resistor and logic thresholds (VIL ≤ 0.4V, VIH ≥ 1.2V) for reliable shutdown control.
It operates across –40°C to 125°C junction temperature, supports stable regulation with only 1µF ceramic input and output capacitors, and enables remote output capacitor placement up to 10cm from the device - enabled by internal compensation and low-ESR stability design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.2V ±2% - ensures precise biasing for 3.3V-tolerant analog/RF ICs without external feedback network. |
| Max output current | 250mA - sufficient for powering RF transceivers, ADCs, or sensor signal chains in portable systems. |
| Dropout voltage | 120mV (typical @ 250mA, DSBGA) - enables operation from 3.3V supply down to 3.32V input while maintaining regulation. |
| Output noise | <6.5µVRMS (10Hz–100kHz) - eliminates need for noise-bypass capacitor, reducing BOM count and PCB area. |
| PSRR | 82dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding sensitive analog circuits. |
| Quiescent current | 12µA (enabled, IOUT = 0mA) - extends battery life in always-on sensor or IoT endpoint applications. |
| Input voltage range | 2.2V to 5.5V - compatible with single-cell Li-ion (3.0–4.2V), USB (5V), or multi-cell alkaline supplies. |
Pinout & Package
X2SON-4 (DQN) package: 1mm × 1mm footprint, no thermal pad required; GND-connected thermal pad recommended but optional. Compatible with high-density layouts and reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers stable 3.2V; connects to load; internal 230Ω pulldown discharges output when disabled. |
| 2 (GND) | Ground reference | Common return path for input, output, and enable; must be low-impedance analog ground. |
| 4 (IN) | Input supply | Accepts 2.2–5.5V; requires ≥1µF ceramic capacitor placed ≤1cm from pin for stability. |
| 3 (EN) | Enable control | Active-high logic input; 1MΩ internal pulldown holds regulator off at power-up; VIH ≥ 1.2V enables. |
Key Features
| Feature | Design Value |
|---|---|
| Noise-bypass capacitor elimination | Integrated RC filter reduces reference noise to <6.5µVRMS, removing need for external 10nF–100nF bypass cap and associated layout constraints. |
| Remote output capacitor support | Stable with 1µF ceramic output cap placed up to 10cm from OUT pin - enables flexible PCB routing for EMI-sensitive loads. |
| Low-IQ with fast enable | 12µA quiescent current and 80–150µs turn-on time allow efficient always-on operation with rapid wake-up response. |
| Thermal & short-circuit protection | Auto-shutdown at ~160°C junction temp with 15°C hysteresis; current limit clamps output at 250–500mA to prevent damage during fault conditions. |
| Ultra-small X2SON-4 package | 1mm × 1mm footprint with 0.5mm pitch - reduces board area by >50% vs SOT-23-5 while maintaining thermal performance (RθJA = 216.1°C/W). |

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 |
|---|---|---|---|
| TPL7407LPGEDR | 200mA max output, 15µVRMS noise, 1.8V–5.5V input, same X2SON-4 package | Higher noise floor limits use in ultra-sensitive RF sections; better suited for general-purpose MCU I/O rails | Select when lower cost and adequate noise performance suffice; verify 200mA margin meets peak load demand. |
| TPS7A2025PDQNR | 300mA max output, 3.8µVRMS noise, 1.6V–6.0V input, same X2SON-4 package | Superior noise and higher current support more demanding RF/analog loads; requires 2.5V output vs 3.2V | Choose for next-gen designs needing tighter noise specs; confirm system-level compatibility with 2.5V instead of 3.2V rail. |
Compared with LP5907UVE-3.2/NOPB, TPL7407LPGEDR trades noise performance for cost in non-critical rails, while TPS7A2025PDQNR delivers lower noise and higher current at the expense of output voltage mismatch - requiring schematic revision if replacing directly.

FAQ
What is the maximum ambient temperature for continuous operation of LP5907UVE-3.2/NOPB in a standard PCB layout?
The LP5907UVE-3.2/NOPB supports ambient temperatures up to +85°C under recommended operating conditions. At higher power dissipation, derating is required using TA-MAX = 125°C – (RθJA × PD). For the X2SON-4 package (RθJA = 216.1°C/W), sustained 250mA at 3.3V input yields ~250mW dissipation, limiting safe ambient to ~70°C without thermal enhancement. LP5907UVE-3.2/NOPB datasheet Section 5.3 confirms this TA range.
Does LP5907UVE-3.2/NOPB require an external noise-bypass capacitor?
No, LP5907UVE-3.2/NOPB does not require an external noise-bypass capacitor. Its internal low-pass RC filter (–3dB at ~0.1Hz) reduces reference noise sufficiently to achieve <6.5µVRMS output noise with only 1µF input and output ceramic capacitors. This is explicitly stated in the Features and Description sections of the LP5907UVE-3.2/NOPB datasheet.
Can the output capacitor for LP5907UVE-3.2/NOPB be placed remotely from the IC?
Yes, LP5907UVE-3.2/NOPB supports remote output capacitor placement up to 10cm from the device, as confirmed in Section 6.3.4 and Figure 7-1 of the LP5907UVE-3.2/NOPB datasheet. This capability is enabled by internal compensation and stability design, allowing the 1µF ceramic output capacitor to be located directly at the load for optimal high-frequency decoupling.
What is the enable pin behavior during power-up for LP5907UVE-3.2/NOPB?
The LP5907UVE-3.2/NOPB EN pin has an internal 1MΩ pulldown resistor, ensuring the device remains disabled until a valid high-level signal (>1.2V) is applied. This prevents uncontrolled output activation during system power ramp-up. The LP5907UVE-3.2/NOPB also features automatic output discharge via a 230Ω internal pulldown when EN is low, safely draining residual charge from the output node.
Is LP5907UVE-3.2/NOPB compatible with ceramic capacitors having 20% tolerance?
Yes, LP5907UVE-3.2/NOPB is compatible with X7R/X5R ceramic capacitors rated at ±20% tolerance, provided the minimum capacitance (0.7µF) is maintained across the full operating temperature and voltage range. The LP5907UVE-3.2/NOPB datasheet Section 5.6 specifies that capacitor tolerance must be "30% or better" - making ±20% X7R acceptable for most applications.
