LD29150

1.5 A, very low drop voltage regulators

Datasheet

production data

Features

• Very low dropout voltage (typ. 0.4 at 1.5 A)

• Guaranteed output current up to 1.5 A

• Fixed and adjustable output voltage (± 1% at

25 °C)

• Internal current and thermal limit

• Logic controlled electronic shutdown available

in PPAK and P²PAK

Description

The LD29150 is a high current, high accuracy,

low-dropout voltage regulator series. These

regulators feature 400 mV dropout voltage and

very low ground current. Designed for high

current loads, these devices are also used in

lower current, extremely low dropout-critical

systems, where their 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.
