The TLV742P series of low-dropout linear voltage regulators (LDOs) are optimized toproviding excellent performance by supporting a wide output voltage range. The LDOs can directlyregulate a single cell Li-ion battery input-to-output voltage as low as 0.85 V.  If used topost-regulate a DC-DC converter output, the high PSRR of 55 dB at 1 MHz suppresses ripple toprovide a stable low-noise, well-regulated VOUT.

The TLV742P has an active output discharge feature that helps ensure the output is keptlow while the system is disabled, in standby mode, or in sleep mode.  Additionally, overcurrentprotection is present to protect the device in the event of an output short along with thermalshutdown to prevent overheating.

The TLV742P series of voltage regulators are available in a 1 mm × 1 mm X2SON package tominimize PCB area.
