Product Introduction
The TLV757P low-dropout regulator (LDO) is an ultrasmall, 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 IQ 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.

Frequently Asked Questions
What fixed output voltage, maximum load current, and input operating limits define the TLV75733PDBVR LDO regulator?
The Texas Instruments TLV75733PDBVR is a low-dropout linear regulator that provides a fixed 3.3 V output with ±1% output accuracy. It operates from an input voltage range of 1.45 V to 5.5 V and delivers up to 1.0 A of continuous output current while providing good line and load transient performance for powering microcontrollers and other low-voltage digital circuits.
What maximum dropout voltage, supply quiescent current, and power-saving features govern this power regulator?
The device features a low quiescent current of 25 µA typical (40 µA maximum over the operating temperature range) to minimize standby power consumption. At a 1.0 A load with a 3.3 V output, the maximum dropout voltage is 425 mV (or 475 mV across the full junction temperature range), helping maintain regulation when the input voltage is close to the output voltage.
Which physical package dimensions, lead layout codes, and part-number suffixes specify this component?
The orderable part number TLV75733PDBVR identifies a 3.3 V fixed-output member of the TLV757P regulator family. The "P" suffix indicates active output discharge, "DBV" specifies the 5-pin SOT-23 surface-mount package, and "R" denotes reel packaging (3,000 pieces). The SOT-23 package has nominal body dimensions of 2.90 mm × 1.60 mm with a 0.95 mm pin pitch.
