Product details
Overview
LP5907UVE-3.3/NOPB from Texas Instruments is a 250mA, low-noise, low-IQ LDO voltage regulator delivering a fixed 3.3V 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 LP5907UVE-3.3/NOPB datasheet, LP5907UVE-3.3/NOPB pinout, LP5907UVE-3.3/NOPB application, or LP5907UVE-3.3/NOPB equivalent, this page delivers 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 parts for design flexibility.
Technical Context
The LP5907UVE-3.3/NOPB employs a proprietary low-noise reference architecture with integrated RC filtering (–3dB at ~0.1Hz) to achieve <6.5µVRMS noise without external bypass capacitors. 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/output capacitors, and features an internal 230Ω output pulldown for automatic discharge during disable - enabling safe sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% - ensures precise biasing for 3.3V I/O interfaces and analog sensors without external feedback. |
| Max Output Current | 250mA - sufficient for powering RF transceivers, ADCs, or small microcontrollers in portable devices. |
| Quiescent Current | 12μA (enabled) - enables >1-year battery life in always-on IoT sensor nodes with intermittent wake-up cycles. |
| Output Noise | <6.5µVRMS (10Hz–100kHz) - meets stringent spectral purity requirements for RF front-end power supplies. |
| PSRR | 82dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Dropout Voltage | 120mV @ 250mA (DSBGA); 250mV @ 250mA (SOT-23/X2SON) - allows operation from single-cell Li-ion (3.0V min) while maintaining regulation. |
| Input Voltage Range | 2.2V to 5.5V - compatible with wide-input buck regulators, USB-powered systems, and multi-cell battery packs. |
Pinout & Package
LP5907UVE-3.3/NOPB uses the X2SON-4 (DQN) package: 1.0mm × 1.0mm, 0.5mm pitch, bottom-side thermal pad (recommended connected to GND). This ultra-compact, leadless package supports high-density PCB layouts and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers stable 3.3V; connects directly to load; supports remote capacitor placement up to 10cm away. |
| 2 (GND) | Power ground | Common return path for input, output, and enable; thermal pad must be soldered to GND plane for optimal thermal performance. |
| 3 (EN) | Enable control input | Active-high logic input (VIH ≥ 1.2V); internal 1MΩ pulldown holds device off at power-up; enables system-level power sequencing. |
| 4 (IN) | Unregulated input | Accepts 2.2–5.5V supply; requires ≥1µF ceramic capacitor placed ≤1cm from pin for transient stability. |
Key Features
| Feature | Design Value |
|---|---|
| Noise-bypass-capacitor-free operation | Integrated RC-filtered reference eliminates need for dedicated 10nF–100nF noise capacitor - reduces BOM count and board area. |
| Remote output capacitor placement | 1µF ceramic output capacitor can be located up to 10cm from device - simplifies layout in stacked or flex-based designs. |
| Automatic output discharge | 230Ω internal pulldown discharges VOUT when EN is low - prevents floating outputs and ensures clean power-down sequencing. |
| Thermal overload protection | Shuts down at TJ ≈ 160°C with 15°C hysteresis - protects against sustained overloads without requiring external thermal monitoring. |
| Stable with minimal capacitance | Guaranteed stability with 1µF ±30% X7R ceramic input/output caps - avoids costly high-ESR or specialized low-ESR capacitors. |
Applications
| Smartphone RF Power Rail | Digital Still Camera Sensor Bias |
|---|---|
|

| Industrial IoT Sensor Node | Factory Automation PLC I/O Module |
|
Use Scenario: Powers ultra-low-power microcontroller and sub-GHz RF transceiver in battery-operated environmental sensor nodes deployed for years. IC Role / Device Role / Timing Role: Primary system LDO; enables long-term operation via 12μA quiescent current and fast enable/disable control. Use Value: 12μA IQ extends 2000mAh coin-cell lifetime to >10 years in sleep mode; remote capacitor placement eases integration into sealed enclosures. |
Use Scenario: Provides isolated 3.3V supply for digital I/O buffer ICs and level translators in modular PLC backplanes exposed to industrial EMI. IC Role / Device Role / Timing Role: EMI-hardened local regulator; decouples noisy digital logic from sensitive analog measurement circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A2033PDBVR | Lower IQ (6.5μA), higher PSRR (95dB @ 1kHz), same 3.3V output, but requires minimum 0.5µF output cap (vs 1µF for LP5907). | Better suited for ultra-low-power wearables; less tolerant of aging/capacitance drift due to lower COUT requirement. | Select TPS7A2033PDBVR when minimizing standby current is primary; verify capacitor aging margin in 10+ year deployments. |
| MCP1700T-3302E/MB | Higher dropout (330mV @ 250mA), higher noise (25µVRMS), no EN pin, SOT-23-3 package - simpler but lower performance. | Targeted at cost-sensitive, non-RF applications like basic MCU power where noise and PSRR are secondary. | Choose MCP1700T-3302E/MB only for legacy designs or non-critical rails; avoid in RF/analog signal chains. |
Compared with TPS7A2033PDBVR and MCP1700T-3302E/MB, LP5907UVE-3.3/NOPB offers the optimal balance of ultra-low noise, industry-standard 1µF capacitor compatibility, and integrated enable/discharge - making it the preferred choice for new RF and precision analog designs where layout flexibility and signal integrity are prioritized over absolute minimum IQ.

FAQ
What is the maximum output current rating for LP5907UVE-3.3/NOPB?
The LP5907UVE-3.3/NOPB is rated for a continuous output current of 250mA under recommended operating conditions (TJ ≤ 125°C). This value is validated across all supported packages (X2SON, DSBGA, SOT-23) and remains stable across the full input voltage range (2.2V–5.5V) and temperature range (–40°C to 125°C). Derating applies above 85°C ambient depending on PCB thermal design.
Does LP5907UVE-3.3/NOPB require an external noise bypass capacitor?
No, LP5907UVE-3.3/NOPB does not require an external noise bypass capacitor. Its internal low-pass RC filter (–3dB at ~0.1Hz) on the reference voltage achieves <6.5µVRMS output noise without additional capacitance - a key differentiator confirmed in TI's SNVS798Q datasheet Section 6.3.2 and Figure 5-17.
What is the function of the EN pin on LP5907UVE-3.3/NOPB?
The EN pin on LP5907UVE-3.3/NOPB is an active-high enable input with internal 1MΩ pulldown. When pulled ≥1.2V (VIH), the regulator enables and delivers 3.3V; when ≤0.4V (VIL), it disables and activates the 230Ω internal pulldown to discharge VOUT - enabling controlled power sequencing in multi-rail systems.
Can the output capacitor for LP5907UVE-3.3/NOPB be placed remotely?
Yes, LP5907UVE-3.3/NOPB supports remote output capacitor placement up to 10cm from the device, as explicitly stated in Section 6.3.4 of the datasheet. This capability is enabled by its robust stability design with 1µF ceramic output capacitance and is validated for use in flex-to-PCB or stacked-module configurations.
What package type is used by LP5907UVE-3.3/NOPB?
LP5907UVE-3.3/NOPB uses the X2SON-4 (DQN) package: 1.0mm × 1.0mm body, 0.5mm pitch, with an exposed thermal pad on the bottom side. This package is distinct from the SOT-23-5 and DSBGA variants and is specified in TI's Mechanical, Packaging, and Orderable Information document for this exact part number.
