The TLV2217-25PW is a PMIC, or power management IC, from Texas Instruments. It is part of TI\'s family of linear voltage regulators, designed to help designers preserve energy resources while providing a safe and reliable power supply to a variety of applications.The TLV2217-25PW is a low-dropout, adjustable linear voltage regulator with low quiescent current and wide input voltage range. It provides up to 25 mA output current and is offered in the 3- Terminal TO-92 package. The device requires an input voltage of 2.5 V to 6.5 V and delivers an output voltage of 1.235 V to 5.0 V in steps of 25 mV.The TLV2217-25PW offers an industry-leading quiescent current of only 100 μA as well as low power dissipation of 0.4 mW (typical) at 25 mA output current. It is also available in an extended temperature range from -20°C to +85°C.The TLV2217-25PW is ideal for a wide range of applications requiring reliable and low cost power supply, such as digital cameras, cell phones, PDAs, media players, and miniature electronic devices. Specific applications for the TLV2217-25PW include digital voltage regulation, battery-powered applications, microprocessors and controllers, logic level shifting, level shifting and scaling, and low noise amplification.The TLV2217-25PW utilizes a standard three-terminal configuration, using an input voltage pin (IN), a ground pin (GND), and an output voltage pin (OUT). The device is designed to be connected to the input voltage source, such as a battery or a regulated power supply. The output voltage can then be adjusted by changing the value of the external resistor, connected between IN and GND.The working principle of the TLV2217-25PW is to control the output voltage by monitoring the voltage drops across the ground and output pins. The output voltage is regulated by the device to within ±2% of the set point over line, load, and temperature conditions. To ensure long-term stability, an external bypass capacitor is recommended, though not mandatory. Typical dropout voltage for the device is only 0.1V at 25 mA load current, and the typical voltage regulation is better than 0.8%. The device also has good load and line transient responses, making it suitable for use in low noise applications.In summary, the TLV2217-25PW is a PMIC, linear voltage regulator offering low dropout voltage and wide input voltage range, and allowing up to 25 mA output current. Its low quiescent current, low power dissipation and extended temperature range make it ideal for a wide range of power management applications, such as battery-powered devices, mobile phones, and PDAs.
