Product Description

The MP20048 is a kind of new low-dropout (LDO) voltage regulators which uses an NMOS as the pass element in a voltage-follower configuration. It can get any value of output from 1.234V to 5V. The benefit of this product is that it can operate without any capacitors. The MP20048 uses an advanced BICMOS process to yield high precision. It also delivers very low dropout voltage and low ground pin current. It integrates the thermal-off and current limit block to protect the devices from damage. The MP20048 is available in a TSOT23-5 package.
