The AP2210 from Diodes Incorporated is a ULDO Voltage Regulator that is ideal for cellular phones, cordless phones, wireless communications, PDAs, palmtops, PC motherboards, and consumer electronics applications. It requires an input voltage of 2.5 - 13.2 V. This LDO provides an output voltage of 1.25 - 13.2 V and has a dropout voltage of 250 mV. It is designed to offer excellent ESR stability with high output accuracy and good ripple rejection, thereby ensuring a stable performance over the input voltage range. This RoHS-compliant regulator offers individual logic compatible enable/shutdown control inputs, over-current protection (OCP), over-temperature protection (OTP), reverse current protection, and thermal protection to prevent short-circuit related damages. It is available in a surface-mount package that measures 2.82 x 2.65 x 1.45 mm.
