Product details
Overview
LP5907UVX-2.85/NOPB from Texas Instruments is a 250mA, low-noise, low-IQ linear regulator optimized for RF and analog circuits. It delivers a fixed 2.85V output with ±2% tolerance, 12μA quiescent current (enabled), <6.5µVRMS output noise, and 82dB PSRR at 1kHz - enabling clean power for smartphone baseband processors and camera sensor rails.
For engineers reviewing the LP5907UVX-2.85/NOPB datasheet, LP5907UVX-2.85/NOPB pinout, LP5907UVX-2.85/NOPB application, or LP5907UVX-2.85/NOPB equivalent, key selection criteria include dropout voltage (120mV @ 250mA), remote capacitor placement capability (≤10cm), thermal shutdown threshold (160°C), and compatibility with 1µF ceramic input/output capacitors without bypass requirements.
Technical Context
The LP5907UVX-2.85/NOPB employs a PMOS pass transistor architecture with internal 1MΩ EN pulldown and 230Ω output discharge resistor, enabling fast enable/disable control and automatic VOUT discharge during shutdown. Its low-noise design uses an integrated first-order RC filter (–3dB ≈ 0.1Hz) on the reference path to suppress internal bandgap noise before amplification.
It operates across –40°C to 125°C junction temperature, supports input voltages from 2.2V to 5.5V, and maintains regulation with only 1µF ceramic input and output capacitors - eliminating need for external noise-bypass caps while allowing remote output capacitor placement up to 10cm from the IC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85V ±2% - ensures stable bias for 2.8V–2.9V logic domains and image sensor analog front-ends. |
| Max Output Current | 250mA - sufficient for powering single-core application processors or multi-channel ADCs in portable devices. |
| Quiescent Current | 12μA (enabled) - enables >1-year battery life in always-on sensor nodes and low-power IoT wake-up circuits. |
| Dropout Voltage | 120mV (typical @ 250mA, DSBGA package) - allows operation from 3.0V supply while maintaining 2.85V output under full load. |
| Output Noise | <6.5µVRMS (10Hz–100kHz) - meets stringent RF PLL and high-resolution SAR ADC noise floor requirements without external filtering. |
| PSRR | 82dB @ 1kHz - rejects switching noise from adjacent DC/DC converters feeding shared battery rails. |
| Enable Threshold | VIH = 1.2V, VIL = 0.4V - compatible with 1.8V/3.3V GPIOs and supports direct connection to microcontroller reset outputs. |
Pinout & Package
LP5907UVX-2.85/NOPB is packaged in a 4-pin DSBGA (YKE/YKG/YKM/YCR) measuring 0.685mm × 0.685mm with bottom-side solder balls. This ultra-compact wafer-level chip-scale package supports high-density mobile PCB layouts and requires no thermal pad connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (IN) | Input voltage supply | Accepts 2.2V–5.5V; requires ≥1µF ceramic capacitor placed ≤1cm from pin to ensure stability and transient response. |
| A2 (OUT) | Regulated output | Delivers fixed 2.85V; supports remote capacitor placement up to 10cm; includes 230Ω internal pulldown for automatic discharge when disabled. |
| B1 (EN) | Enable control input | Active-high; internally pulled down by 1MΩ resistor; VIH ≥1.2V ensures reliable turn-on across temperature and process variation. |
| B2 (GND) | Power ground reference | Common return path for input, output, and enable circuitry; must connect to low-impedance analog ground plane. |
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 saving board space. |
| Remote output capacitor support | Stable operation with 1µF ceramic cap placed up to 10cm from OUT pin - simplifies layout in stacked-flex or modular designs. |

FAQ
What is the maximum input voltage rating for LP5907UVX-2.85/NOPB?
The absolute maximum input voltage for LP5907UVX-2.85/NOPB is 6V, but the recommended operating range is 2.2V to 5.5V. Exceeding 5.5V may trigger internal protection or reduce reliability. The device requires VIN ≥ (2.85V + VDO) to maintain regulation - with typical dropout of 120mV at 250mA, minimum functional input is ~2.97V under full load.
Does LP5907UVX-2.85/NOPB require an external noise-bypass capacitor?
No, LP5907UVX-2.85/NOPB does not require an external noise-bypass capacitor. Its internal RC-filtered reference architecture achieves <6.5µVRMS output noise (10Hz–100kHz) without additional capacitance - a key differentiator versus legacy LDOs that mandate 10nF–100nF bypass caps on the output or reference pin.
What is the thermal shutdown behavior of LP5907UVX-2.85/NOPB?
LP5907UVX-2.85/NOPB activates thermal shutdown at approximately 160°C junction temperature and re-enables when junction cools to ~145°C (15°C hysteresis). This cycling protects against temporary overloads but is not a substitute for proper thermal design - continuous tripping degrades long-term reliability and indicates insufficient PCB copper area or airflow.
Can the output capacitor be placed remotely from LP5907UVX-2.85/NOPB?
Yes, LP5907UVX-2.85/NOPB supports remote placement of its 1µF ceramic output capacitor up to 10cm from the OUT pin. This capability is validated across temperature and load conditions and enables flexible mechanical routing in multi-board or flex-cable assemblies - such as separating camera sensor and main processor PCBs in smartphones.
What is the enable pin behavior and internal pull-down value for LP5907UVX-2.85/NOPB?
The EN pin of LP5907UVX-2.85/NOPB has an internal 1MΩ pull-down resistor to GND, ensuring default disable state at power-up. It is active-high with VIH ≥ 1.2V and VIL ≤ 0.4V. When pulled low, the device disables and activates a 230Ω internal pulldown on the OUT pin to discharge residual voltage - critical for safe power sequencing in multi-rail systems.
