Description

General part information

TPS7A20U Series

The TPS7A20U is an ultra-small, low-dropout (LDO) linear regulator that sources 75mA of output current. The TPS7A20U is designed to provide low noise, high PSRR, and excellent load and line transient performance. This performance meets the requirements of RF and other sensitive analog circuits. Using innovative design techniques, the TPS7A20U offers ultra-low noise performance without the addition of a noise bypass capacitor. The TPS7A20U also provides the advantage of low quiescent current, which is designed for battery-powered applications. With a 1.6V to 6.0V input voltage range and a 0.8V to 5.5V output range, the TPS7A20U is applicable 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 TPS7A20U 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 TPS7A20U has a smart enable input circuit with an internally controlled pulldown resistor that keeps the LDO disabled. The LDO remains disabled even when the EN pin is left floating and helps eliminate the external components used to pulldown the EN pin.
