General Description
The RT9094A is a very low dropout linear regulator which
operates from input voltage as low as 0.8V. The device
capable of supplying 2A of output current with a typical
dropout voltage of only 100mV. A VBIAS supply is required
to run the internal reference and LDO circuitry while output
current comes directly from the VIN supply for high
efficiency regulation. User-programmable soft-start limits
the input inrush current and minimizes stress on the input
power. The enable input and power good output allow easy
sequencing with external regulators. This complete
flexibility provides an easy-to-use robust power
management solution for a wide variety of applications.
The RT9094A is stable with output capacitor greater than
or equal to 2.2μF. A precise reference and error amplifier
deliver 2% accuracy over load, line and temperature. Overcurrent
limit and over-temperature protection are also
included. The RT9094A is available in the WDFN-10L 3x3
package.
