3 Description

The TPS7A20L is an ultra-small, low-dropout (LDO) linear regulator that can source 300mA of output current. The TPS7A20L 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 TPS7A20L offers an ultra-low noise performance without the addition of a noise bypass capacitor. The TPS7A20L also provides the advantage of low quiescent current, which can be beneficial for battery-powered applications. With an input voltage range of 1.6V to 6.0V and an output range of 0.8V to 5.5V, the TPS7A20L 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 TPS7A20L 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 TPS7A20L 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. The enable input logic thresholds are compatible with the output levels of 1.2V logic devices.
