Description for the TLV755P

The TLV755P is an ultra-small, low quiescent current, low-dropout regulator (LDO) thatsources 500 mA with good line and load transient performance. The TLV755P is optimized for a 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 microcontrollers (MCUs). Additionally, the TLV755P has alow I_Q with enable functionality to minimize standby power. This devicefeatures an internal soft-start to lower inrush current, thus providing a controlled voltage to theload and minimizing the input voltage drop during start up. When shutdown, the device activelypulls down the output to quickly discharge the outputs and ensure a known start-up state.

The TLV755P 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 TLV755P has an internal foldback current limit that helps reduce the thermal dissipation duringshort-circuit events.
