詳細說明
When it comes to efficiency and effectiveness, the TPS76801QPWP sets a new standard. Its advanced design allows for a quick transient response and stable operation with 10 µF capacitors, delivering superior performance without breaking the bank. The PMOS pass element, functioning like a low-value resistor, contributes to an ultra-low dropout voltage of just 230 mV at 1 A output current (for the TPS76850 model). The regulator also boasts a meager quiescent current of 85 µA, regardless of the load, ensuring optimal energy conservation. Additionally, the inclusion of a shutdown mode and a power good (PG) output further enhances the product's versatility and usability in various applications

常見問題解答
What is TPS76801QPWP?
The TPS76801QPWP is a low-dropout (LDO) voltage regulator designed by Texas Instruments. It is a high-performance, fixed-output voltage regulator capable of delivering up to 1A of continuous output current. The device is suitable for a wide range of applications where low dropout voltage and low quiescent current are important, such as automotive electronics, industrial control systems, and battery-powered equipment.
How Does TPS76801QPWP Work?
The TPS76801QPWP operates by regulating an input voltage to a specified output voltage with minimal dropout voltage. It maintains a stable output voltage even when the input voltage decreases close to the output voltage level. The device features low quiescent current, making it suitable for battery-operated applications where power efficiency is crucial.
How Many Pins does TPS76801QPWP have and What are the Functions of the Pinout Configuration?
The TPS76801QPWP is housed in a 20-pin HTSSOP (PowerPAD) package. The pinout configuration includes:
- IN: Input voltage pin.
- GND: Ground pin.
- EN: Enable pin for controlling the regulator's output.
- NC: No-connect pin.
- PGND: Power ground pin.
- FB: Feedback pin for setting the output voltage.
- FLT: Fault status pin for error reporting.
- REG: Regulator output voltage pin.
What are the Pros and Cons of TPS76801QPWP?
Pros:
- High Output Current: Capable of delivering up to 1A of continuous output current.
- Low Dropout Voltage: Maintains stable output voltage with minimal dropout, suitable for low input voltage applications.
- Low Quiescent Current: Offers power efficiency in battery-operated devices.
- Thermal Shutdown and Overcurrent Protection: Built-in features for enhanced reliability and safety.
- Compact Package: The HTSSOP package enables space-efficient designs.
Cons:
- Heat Dissipation: May require additional thermal management for high-power applications.
- External Capacitors: Requires input and output capacitors for stable operation, adding to the overall system cost and board space.
Are There Any Equivalents/Alternatives to TPS76801QPWP for Recommendation?
- The TPS79901-Q1 from Texas Instruments is a similar LDO voltage regulator designed for automotive applications.
- Alternatives to the TPS76801QPWP include the MIC29302 from Microchip Technology and the LT1963A from Analog Devices.
