Product Introduction

The PJ20301 is a 3 A low dropout linear regulator designed for low dropout and high current applications. This device works with dual supplies, a control input for the control circuitry and a power input as low as 1.0 V for providing current to output. It features 3 A output current and ultra-low-drop output voltage as well as full protection functions. VOUT can be as low as 0.8V. The other features include soft start, under voltage protection, current limit protection, Power-On-Reset function, and over temperature protection. The PJ20301 is available in DFN3x3- 10 and PSOP-8 packages.
