3 Description

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, wellregulated

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.
