LD29300 3 A, very low drop voltage regulator Datasheet - production data Table 1. Device summary Order codes Output voltages LD29300P2MTR ADJ P²PAK Features  Very low dropout voltage (typ. 0.4 V at 3 A)  High accuracy: ±1% @ 25°C  Guaranteed output current up to 3 A  Internal current and thermal limit  Logic controlled electronic shutdown Description The LD29300 is a high current, high accuracy, low-dropout voltage regulator. This regulator features 400 mV dropout voltage and very low ground current. Designed for high current loads, this device is also used in lower current, extremely low dropout-critical systems, where its tiny dropout voltage and ground current values are important attributes. Typical applications are in power supply switching post regulation, series power supply for monitors, series power supply for VCRs and TVs, computer systems and battery-powered systems.
