TPS71727DCKRG4 Description

The TPS71727DCKRG4 low-dropout (LDO), low-power linear regulators offer very high power-supply rejection (PSRR) while maintaining a very low 45-μA ground current in an ultra-small, five-pin SOT package. The family uses an advanced BiCMOS process and a PMOS pass device to achieve fast start-up, very low noise, excellent transient response, and excellent PSRR performance. The TPS71727DCKRG4 is stable with a 1-μF ceramic output capacitor and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% over all load, line, process, and temperature variations.
