Description

General part information

TPS7A20C Series

The TPS7A20C is an ultra-small, low-dropout (LDO) linear regulator that sources 300mA of output current. This LDO is designed to power sensitive loads such as image sensors. When used with low output capacitance and inductance, the device provides low noise, high PSRR, and excellent load and line transient performance. Using innovative design techniques, the TPS7A20C offers ultra-low noise performance without the addition of a noise-bypass capacitor. The TPS7A20C also provides the advantage of low quiescent current, which is useful in battery-powered applications. The 1.6V to 6.0V input voltage range and 0.8V to 5.5V output range are appropriate 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 TPS7A20C features an internal soft-start circuit 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 TPS7A20C has a smart enable input circuit with an internally controlled pulldown resistor. This resistor keeps the LDO disabled and helps eliminate the external components used to pulldown the EN pin. The LDO remains disabled even when the EN pin is left floating.
