General Description

Features

The TD5860/TD5860A linear regulator is designed to

provide a regulated voltage with bi-direction output

current for DDRSDRAM termination voltage. The

TD5860 integrates two power transistors to source or

sink load current up to 1.5A/2A. It also features internal

soft-start, current-limit, thermal shutdown and enable

control functions into a single chip.

Soft-Start

Power-On-Reset Monitoring on VCNTL and VIN

pins

Fast Transient Response

System Output Accuracy over Load and

Temperature Ranges

The internal soft-start controls the rising rate of the

output voltage to prevent inrush current during start-up.

The current-limit circuit detects the output current and

limits the current during short-circuit or current overload

conditions. The on-chip thermal shutdown provides

thermal protection against any combination of overload

that would create excessive junction temperatures.

The output voltage of TD5860/TD5860A is regulated to

track the voltage on VREF pin. An proper resistor divider

connected to VIN, GND, and VREF pins is used to

provide a half voltage of VIN to VREF pin. In addition,

connect an external ceramic capacitor and a open-drain

transistor to VREF pin for external soft-start and

shutdown control.

Packages

Lead Free and Green Devices Available(RoHS

Compliant)

Applications

Pulling and holding the voltage on VREF below the

enable voltage threshold shuts down the output. The

output of TD5860/TD5860A will be high impedance after

being shut down by VREF or the thermal shutdown

function.
