TLV742P Low-Dropout Linear Voltage Regulators Texas Instruments TLV742P Low-Dropout Linear Voltage Regulators (LDOs) are optimized to provide excellent performance by supporting a wide output voltage range. These LDOs can directly regulate a single-cell Li-ion battery input-to-output voltage as low as 0.85V. If used to post-regulate a DC-DC converter output, the high PSRR of 55dB at 1MHz suppresses ripple to provide a stable, low-noise, well-regulated VOUT.
