EUP7212

Preliminary EUP7212 Dual 150/300mA LDO with POR DESCRIPTION The EUP7212 is a dual low dropout linear regulator. The first regulator is capable of sourcing 150mA, while the second regulator can source up to 300mA and includes a power-on reset function. The EUP7212 is stable with small ceramic output capacitors. The performance of EUP7212 is optimized for battery power systems to deliver low noise, low dropout voltage, low quiescent current and excellent line and load transient response. www.DataSheet4U.com The EUP7212 is available in fixed output voltages in the 8-pin 3mm¡Ñ 3mm DFN leadless package.
