The TLV757P low-dropout regulator (LDO) is an ultra-small, low quiescent current LDO thatsources 1 A with good line and load transient performance. The TLV757P is optimized for widevariety of applications by supporting an input voltage range from 1.45 V to 5.5 V. To minimize costand solution size, the device is offered in fixed output voltages ranging from 0.6 V to 5 V tosupport the lower core voltages of modern MCUs. Additionally, the TLV757P has a lowIQ with enable functionality to minimize standby power. This device featuresan internal soft-start to lower the inrush current which provides a controlled voltage to the loadand minimizes the input voltage drop during start up. When shutdown, the device actively pulls downthe 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 overallsolution size. A precision band-gap and error amplifier provides a typical accuracy of 1%. Alldevice 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 dissipationduring short circuit events.
