AX1201

1A Ultra Low Dropout Linear Regulator



GENERAL DESCRIPTION

The AX1201 is a low-dropout voltage regulator suitable for various electronic

equipments. It provides constant voltage power source. The dropout voltage of AX1201 is

below 0.14V in full rated current (1A). This regulator has various functions such as a peak

current protection, a thermal shut down, a short circuit protect.

The AX1201 is available in SOP-8L and TDFN-8L power packages which features

small size to reduce the junction-to-case resistance, being applicable in 0.5~3W

applications.


