Product details
Overview
LP5907UVE-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 sensitive receivers in portable wireless devices.
For engineers reviewing the LP5907UVE-2.85/NOPB datasheet, LP5907UVE-2.85/NOPB pinout, LP5907UVE-2.85/NOPB application, or LP5907UVE-2.85/NOPB equivalent, key selection criteria include dropout voltage (120mV typ. @250mA), remote output capacitor support (up to 10cm), thermal shutdown (160°C), and compatibility with 1µF ceramic input/output capacitors without bypass requirements.
Technical Context
The LP5907UVE-2.85/NOPB uses an NMOS pass transistor architecture with internal bandgap reference filtering and a first-order RC noise-reduction network (–3dB at ~0.1Hz). Its enable logic includes a 1MΩ internal pulldown resistor and VIH/VIL thresholds of 1.2V/0.4V, supporting direct GPIO control without external pull-downs.
It achieves stable regulation with only 1µF ceramic input and output capacitors due to inherent phase-margin optimization - eliminating need for external noise-bypass caps while permitting remote output capacitor placement up to 10cm from the IC. Thermal protection activates at 160°C with 15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85V ±2% - ensures precise biasing for 2.8V–3.0V logic rails and RF front-end components. |
| Max Output Current | 250mA - sufficient for powering single-core microcontrollers, RF transceivers, or analog sensor signal chains. |
| Quiescent Current | 12μA (enabled) - enables multi-year battery life in always-on IoT sensors and wearable standby modes. |
| Dropout Voltage | 120mV typical @250mA (DSBGA package) - supports operation down to VIN = 2.97V while maintaining regulation. |

FAQ
What is the maximum output current supported by the LP5907UVE-2.85/NOPB?
The LP5907UVE-2.85/NOPB supports a continuous output current of up to 250mA. This rating applies across the full operating temperature range (–40°C to +125°C junction) and is validated for all package variants including the YKE DSBGA used in the LP5907UVE-2.85/NOPB. Current limiting and thermal shutdown protect the device under overload conditions.
Does the LP5907UVE-2.85/NOPB require an external noise-bypass capacitor?
No, the LP5907UVE-2.85/NOPB does not require an external noise-bypass capacitor. Its internal RC filter reduces reference voltage noise to <6.5µVRMS (10Hz–100kHz), enabling clean output with only a 1µF ceramic output capacitor - a key differentiator confirmed in TI's SNVS798Q datasheet Section 6.3.2.
What is the dropout voltage specification for the LP5907UVE-2.85/NOPB at full load?
The LP5907UVE-2.85/NOPB has a typical dropout voltage of 120mV at 250mA output current when using the DSBGA package (YKE/YKG/YKM/YCR). This value is specified in the Electrical Characteristics table (Section 5.5) and enables regulation down to VIN = 2.97V while maintaining 2.85V output.
Can the output capacitor of the LP5907UVE-2.85/NOPB be placed remotely from the IC?
Yes, the LP5907UVE-2.85/NOPB supports remote output capacitor placement up to 10cm from the OUT pin, as explicitly stated in Sections 1, 3, and 6.3.4 of the datasheet. This feature is enabled by its internal stability compensation and is verified with 1µF ceramic capacitors meeting ESR specifications (5–500mΩ).
What is the quiescent current of the LP5907UVE-2.85/NOPB in enabled and disabled states?
In enabled state (VEN ≥1.2V), the LP5907UVE-2.85/NOPB draws 12μA typical quiescent current. In disabled state (VEN ≤0.4V), it draws 0.2–1μA, as specified in Section 5.5 Electrical Characteristics. These values are measured at TA = 25°C with IOUT = 0mA and are critical for battery-life calculations in always-on applications.
