General Description

The EC49315 is a low noise 500mA fixed /adjustable output voltage, with high ripple rejection ratio and fast
transient response.
It includes a precise reference voltage, an error amplifier, driver transistors, a compensation network and a low ON-resistance power MOSFET.
It also integrates many protection circuitries, such as current limiters and an over temperature protection module.
The EC49315 workswell with low ESR ceramic capacitors, suitable for battery-powered applications with stringent space requirements and demanding performance.
It also offers low quiescent current.
