Описание

The TLV742P series of low-dropout linear voltage regulators (LDOs) are optimized to providing excellent performance by supporting a wide output voltage range. The LDOs can directly regulate a single cell Li-ion battery input-to-output voltage as low as 0.85 V. If used to post-regulate a DC-DC converter output, the high PSRR of 55 dB at 1 MHz suppresses ripple to provide a stable low-noise, well-regulated VOUT.The TLV742P has an active output discharge feature that helps ensure the output is kept low while the system is disabled, in standby mode, or in sleep mode. Additionally, overcurrent protection is present to protect the device in the event of an output short along with thermal shutdown to prevent overheating.The TLV742P series of voltage regulators are available in a 1 mm × 1 mm X2SON package to minimize PCB area.
