Description for the TPS7A20

The TPS7A20 is an ultra-small, low-dropout (LDO) linear regulator that can source 300 mA of output current. The TPS7A20 is designed to provide low noise, high PSRR, and excellent load and line transient performance that can meet the requirements of RF and other sensitive analog circuits. Using innovative design techniques, the TPS7A20 offers an ultra-low noise performance without the addition of a noise bypass capacitor. The TPS7A20 also provides the advantage of low quiescent current, which can be ideal for battery-powered applications. With an input voltage range of 1.6 V to 6.0 V and an output range of 0.8 V to 5.5 V, the TPS7A20 can be used for a wide variety of applications. The device uses a precision reference circuit to provide a maximum accuracy of 1.5% over load, line, and temperature variations.

The TPS7A20 features an internal soft-start to lower the inrush current, thus minimizing the input voltage drop during start up. The device is stable with small ceramic capacitors, allowing for a small overall solution size.

The TPS7A20 has a smart enable input circuit with an internally controlled pulldown resistor that keeps the LDO disabled even when the EN pin is left floating and helps eliminate the external components used to pulldown the EN pin.

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.
