Linear Regulators (LDO) | NCP1086

1.5 A Adjustable and 3.3 V Fixed Output Linear Regulator

Datasheet

Products

Overview

The NCP1086 linear regulator provides 1.5 A at 3.3 V or adjustable output voltage. The adjustable output voltage device uses two external resistors to set the output voltage within a 1.25 V to 5.5 V range.

The regulators is intended for use as post regulator and microprocessor supply. The fast loop response and low dropout voltage make this regulator ideal for applications where low voltage operation and good transient response are important.

The circuit is designed to operate with dropout voltages less than1.4 V at 1.5 A output current. Device protection includes overcurrent and thermal shutdown.

This device is pin compatible with LT1086 family of linear regulators and has lower dropout voltage.

The regulators are available in TO-220, surface mount D2PAK, and SOT-223 packages.

  • Output Current to 1.5 A
  • Output Accuracy to +/- 1% Over Temperature
  • Dropout Voltage (typical) 1.05 V @ 1.5 A
  • Fast Transient Response
  • Fault Protection Circuitry
    - Current Limit
    - Thermal Shutdown
