Overview

Description

LT1175CS8-5 is Linear Technology’s fixed 5V version of the LT1175 high‑current positive linear regulator. The CS8 suffix indicates the 8‑pin SOIC package.
Key points:
- Fixed 5V output with roughly 5 A continuous capability.
- Built‑in protection: current limit and thermal shutdown; suitable for rugged power rails.
- Input must be above 5V; dropout is typically a couple of volts at high load; adequate heat sinking is recommended.
Typical uses include bench and embedded power supplies, point‑of‑load regulation, and automotive/industrial electronics.
For exact electrical specs, pinout, capacitor requirements, and thermal data, consult the LT1175 datasheet for the -5 fixed‑output variant.

Features

LT1175CS8-5 features:
- Fixed 5V output version of the LT1175 in an 8-pin CS8 package
- 3 A output capability (high-current regulator)
- Low-dropout regulator with good line and load regulation
- Internal current limit and thermal shutdown (protects against overload)
- Safe-area protection and short-circuit tolerance
- Wide input voltage range
- Requires only minimal external components (primarily input/output capacitors)
- Suitable for post-regulation and point-of-load applications

Pinout

- Pin count: 8 pins (CS8 = 8‑pin SOIC).
- Function: Positive voltage regulator (adjustable LDO) with current limit and protection features. Used to regulate input voltage to a stable output voltage.

Manufacturer

- Manufacturer: Linear Technology Corporation (LT), now part of Analog Devices.
- What kind of company: An American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, especially voltage regulators and power-management ICs.

Application

LT1175CS8-5 is a high-current regulator used in switch‑mode DC–DC power supplies. Its features suit:
- High‑efficiency DC‑DC converters for telecom, networking, and data‑center gear
- Point‑of‑load regulation for CPUs/ASICs and other digital peripherals
- Automotive and industrial power management (wide input range, rugged operation)
- Post‑regulation stages in multi‑output supplies
- Battery‑powered and portable devices requiring compact, efficient regulation
In short: robust, adjustable, high‑current regulation for diverse power‑management applications.

Package

8‑pin SOIC (SO‑8) surface‑mount package.
