TPS7B82EVM-024

POWER MANAGEMENT

This user’s guide describes the operational use of the TPS7B82EVM-024 evaluation module (EVM) as a reference design for engineering demonstration and evaluation of the TPS7B8233QKVURQ1, low-dropout linear regulator (LDO). Included in this user’s guide are setup and operating instructions, layout guidelines, a printed circuit board (PCB) layout, a schematic diagram, and a bill of materials (BOM).

Throughout this document, the terms demonstration kit, evaluation board, and evaluation module are synonymous with the TPS7B82EVM-024.

1 Introduction

Texas Instruments' TPS7B82EVM-024 EVM helps design engineers evaluate the operation and performance of the TPS7B82-Q1 linear regulator for possible use in their own circuit application. This particular EVM configuration contains a single 300-mA, high-voltage, ultra-low-IQ, low-dropout regulator for automotive systems. The regulator is capable of delivering up to 300 mA to the load with a wide VIN range of up to 40 V (45 V transient). For stability, use a 2.2-µF (or larger) output capacitor for the TPS7B82-Q1.

1.1 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the TPS7B82EVM-024. Observe all safety precautions.

2 EVM Setup

This section describes how to properly connect and setup the TPS7B82EVM-024, including the jumpers and connectors on the EVM board.

3 Operation

Operate the equipment using the following steps:

1. Turn on the power supplies..

2. Enable the output by jumping J6 (the EN pin) to VIN.

3. Vary the respective load and input voltage, as necessary, for test purposes.
