Description for the TPS745-Q1

The TPS745-Q1 is a 500-mA ultra-low-dropout regulator (LDO) with power-good functionality. This device is available in a small 6-pin, 2-mm × 2-mm WSON package and a small 8-pin, 3-mm × 3-mm VSON package with wettable flanks to facilitate optical inspection. The TPS745-Q1 consumes low quiescent current and provides fast line and load transient performance.

The TPS745-Q1 is a flexible device for post-regulation by supporting an input voltage range from 1.5 V to 6.0 V and an externally adjustable output range of 0.55 V to 5.5 V. The device also features fixed output voltages for powering common voltage rails.

The TPS745-Q1 has a power-good (PG) output that monitors the voltage at the feedback pin to indicate the status of the output voltage. The EN input and PG output can be used for sequencing multiple power supplies in the system.

The TPS745-Q1 is stable with small ceramic output capacitors, allowing for a small overall solution size. A precision band-gap and error amplifier provides high accuracy of ±0.85% (max) at 25°C and ±1.5% (max) over temperature. This device includes integrated thermal shutdown, current limit, and undervoltage lockout (UVLO) features. The TPS745-Q1 has an internal foldback current limit that helps reduce the thermal dissipation during short-circuit events.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
