The EUP7932 is a 2A low-dropout (LDO) linear regulator which features a user-programmable soft-start, an enable input, a fixed or ADJ able output and a power-good output.

EUP7932 works with two input voltages: VCC provides 5V voltage to drive the gate of the N-MOS power transistor, while IN is the input voltage which supplies power to the load. The use of an external bias power allows the part to operate in ultra low IN voltage. The EUP7932 features ultra low dropout, ideal for applications where OUT is very close to IN. Soft start is another character of EUP7932, the soft-start can reduce inrush current of the load capacitors and minimizes stress on the input power source during start-up.

Additionally, the EUP7932 has an enable pin to further reduce power dissipation while shutdown. The EUP7932 provides excellent regulation over variations in line, load and temperature. The EUP7932 provides a power OK signal when the output voltage reaches 90% of its normal value.

The EUP7932 is stable with any Ceramic output capacitor of 2.2µF or more. A precision reference and feedback control deliver 2% accuracy over load, line, and operating temperature ranges. The EUP7932 is available in SOP-8(EP) packages.
