Introduction

TLV2217-33KTPR is a low dropout (LDO) linear voltage regulator. It is part of the Linear Voltage Regulators family, more specifically of the Power Management ICs (PMIC). It is ideal for applications that require low-noise and low-dropout performance with a wide range of input voltage. The TLV2217-33KTPR is designed to provide a regulated output voltage of 3.3 V and offers good line and load regulation, low quiescent current and excellent ripple rejection.

Description

The TLV2217-33KTPR is a high precision, low-dropout linear regulator with an adjustable output voltage. It has a wide input voltage operating range of 2.7 V to 25V and an output voltage of 3.3V, which make it ideal for a wide range of applications. It features a very low quiescent current (2.2 mA typical), making it suitable for mobile, battery-powered applications. The device includes current limiting and thermal shutdown protection to prevent damage in the event of overload. It has a maximum output current of 800 mA and comes in a standard 8-SOP (Small Outline Package) package.

Features

The TLV2217-33KTPR has several features that make it ideal for applications with low-noise and low-dropout performance:
  • Wide input voltage range: 2.7V to 25V
  • Output voltage: 3.3V
  • Maximum output current: 800 mA
  • Low quiescent current: 2.2 mA typical
  • Good line and load regulation
  • Excellent ripple rejection
  • Current limiting & thermal shutdown protection
  • Standard 8-SOP package

Applications

The TLV2217-33KTPR is ideal for applications that requires low-noise, low-dropout performance with a wide range of input voltage. It can be used for quality audio applications, such as low-noise audio preamps, audio amplifiers and CD players. It is also suitable for battery-powered applications, such as mobile phones, PDAs and other handheld devices.

Working Principle

The principle of operation of the TLV2217-33KTPR is based on the basic operational amplifier (op-amp) circuit. A voltage divider is used to customize the output voltage, with the divider ratio determined by two resistors connected to the output pin. The TLV2217-33KTPR is designed with a bandgap reference and a PNP transistor to provide constant voltage regulation. The current limiting and thermal shutdown protection are provided by a current-sensing circuit and a thermal cutoff switch, respectively. The current-sensing circuit is designed to disconnect the load if the output current exceeds a certain level. The thermal cutoff switch is designed to disconnect the load if the die temperature exceeds a certain level.

Conclusion

The TLV2217-33KTPR is a low dropout (LDO) linear voltage regulator that is ideal for applications that require low-noise, low-dropout performance with a wide range of input voltage. It has a wide input voltage operating range of 2.7 V to 25V and an output voltage of 3.3V, and is designed to provide constant voltage regulation with excellent line and load regulation and excellent ripple rejection. It is suitable for audio applications, as well as for battery-powered applications, such as mobile phones, PDAs and other handheld devices.
