TLV75719PDBVR General Description

The TLV757P low-dropout regulator (LDO) is an ultra-small, low quiescent current LDO that sources 1 A with good line and load transient performance. The TLV757P is optimized for wide variety of applications by supporting an input voltage range from 1.45 V to 5.5 V. To minimize cost and solution size, the device is offered in fixed output voltages ranging from 0.6 V to 5 V to support the lower core voltages of modern MCUs. Additionally, the TLV757P has a low I_Q with enable functionality to minimize standby power. This device features an internal soft-start to lower the inrush current which provides a controlled voltage to the load and minimizes the input voltage drop during start up. When shutdown, the device actively pulls down the output to quickly discharge the outputs and ensure a known start-up state.

The TLV757P is stable with small ceramic output capacitors allowing for a small overall solution size. A precision band-gap and error amplifier provides a typical accuracy of 1%. All device versions have integrated thermal shutdown, current limit, and undervoltage lockout (UVLO). The TLV757P has an internal foldback current limit that helps to reduce the thermal dissipation during short circuit events.
