The TPS73501DRBT is a low-dropout (LDO) low-power Linear Regulator offers excellent AC performance with very low ground current. High power-supply rejection ratio, low noise, fast start-up and excellent line and load transient responses are provided while consuming a very low 46µA typical ground current. This device is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a typical dropout voltage of 280mV at 500mA output. It combines the high performance required by many radio frequency and precision analog applications with ultra-low current consumption. High PSRR is provided by a high-gain, high-bandwidth error loop with good supply rejection and very low headroom. The device uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% over all load, line, process and temperature variations. The combination of high performance and low ground current also makes the device an excellent choice for portable applications.
