TLV755P Low IQ Low-Dropout Voltage Regulator

Texas Instruments' TLV755P is an ultra-small, low quiescent current, low-dropout regulator (LDO) that sources 500 mA with good line and load transient performance. The TLV755P is optimized for a 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 microcontrollers (MCUs). The TLV755P has a low I_Q with enable functionality to minimize standby power.

This device features an internal soft-start to lower inrush current providing a controlled voltage to the load and minimizing the input voltage drop during start-up. When shut down, the device actively pulls down the output to quickly discharge the outputs and ensure a known startup state. The TLV755P is stable with small ceramic output capacitors allowing for a small overall solution size. A precision band-gap and error amplifier provide a typical accuracy of 1%. This LDO features integrated thermal shutdown, current limit, and undervoltage lockout (UVLO). The TLV755P has an internal foldback current limit that helps reduce the thermal dissipation during short-circuit events.
