Texas Instruments TLV775 High-PSRR LDO Linear Regulator

Introduction

The Texas Instruments TLV775 is a high-performance Low-Dropout (LDO) linear regulator designed to provide a stable voltage source with exceptional power supply ripple rejection (PSRR). Capable of sourcing up to 500mA of output current, this versatile component is ideal for a wide range of applications, particularly in portable electronic devices.

Part Description

The TLV775 features an input voltage range of 1.5V to 5.5V and a fixed output voltage range from 0.6V to 3.3V, making it suitable for various electronic circuits. Its high PSRR of 60dB at 1kHz and 45dB at 1MHz ensures minimal noise interference, which is crucial for sensitive applications. The internal soft-start circuit helps to reduce inrush current during startup, while the active pulldown circuit ensures a known output state when disabled. The LDO is designed to be stable with small ceramic capacitors, allowing for compact designs. It comes in a 2.9mm x 2.8mm SOT-23 package and operates within a temperature range of -40°C to +125°C.
