LT1529CQ#TRPBF

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT1529CQ#TRPBF is a commercial grade, adjustable 3A low dropout linear regulator manufactured by Analog Devices. It operates with a quiescent current of 50µA and features a shutdown mode reducing consumption to 16µA. The device supports an output voltage range from 3.8V to 14V via the ADJ pin. It provides reverse battery protection and requires a minimum output capacitance of 22µF for stability. The component is housed in a 5-lead TO-220 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Micropower operation with controlled quiescent current that does not rise during dropout conditions
• Integrated reverse battery protection preventing reverse current flow from output to input
• Stable with small ceramic output capacitors as low as 22µF
• Dedicated shutdown pin for active power management

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Battery-powered systems requiring extended operational life
