Product Overview
The LP5907MFX-3.3-NOPB is a Texas Instruments Power_Management power IC and fixed-output low-noise LDO regulator. This option provides a nominal 3.3 V output and supports output current from 0 mA to 250 mA within the recommended operating conditions.
The regulator operates from a 2.2 V to 5.5 V input range and is specified with ±2% output voltage tolerance for VIN from VOUT(NOM) + 1 V to 5.5 V and IOUT from 1 mA to 250 mA. Typical performance includes 0.02 %/V line regulation, 0.001 %/mA load regulation, 90 dB PSRR at 100 Hz, and low output noise of 10 µVRMS at 1 mA or 6.5 µVRMS at 250 mA.
The DBV SOT-23 5-pin package measures 2.9 mm × 2.8 mm and uses ceramic capacitors, with 1 µF at the input and at least 1 µF at the output. Enable thresholds, disabled quiescent current, output discharge, thermal shutdown, and transient specifications support controlled startup and shutdown in low-noise 3.3 V regulated rails.
