ET516XX
General Description

The ET516XX family are the 300mA LDO with auto discharge function. It uses an advanced CMOS process and a PMOSFET pass device to achieve high power supply rejection ratio (PSRR), low noise, low dropout, low ground current, fast start-up and excellent output accuracy.
The ET516XX family are stable with a 1.0μF ceramic output capacitor, uses a precision voltage reference and feedback loop to achieve excellent Regulation and transient response.
The ET516XX family offered in a small SOT23-5 and DFN4 package, which are ideal for small form factor portable equipment.
