TPS75333QPWPR

TPS75333QPWPR Application Field and Working Principle

The Texas Instruments TPS75333QPWPR is a 3.3V adjustable linear voltage regulator designed to support ultra-low-power, space-constrained applications. The device is available in a wide variety of small package options, including a 7-lead Ultra Thin Small Outline Package (UTSOP) and chip-scale packages that are less than half the size of a quad flat package (QFN).

The TPS75333QPWPR regulator has a low dropout voltage that enables it to output a regulated 3.3V (VOUT) with a wide range of input voltages from 0.45V to 5.5V. It has a low operating current of 10uA, which makes it an ideal choice for a variety of low power applications, such as medical, automotive, home entertainment, and industrial equipment.

Working Principle

The TPS75333QPWPR operates in two modes - active and shutdown. In active mode, the device regulates the output voltage (VOUT) using an internal 0.5V reference voltage and a PMOS pass transistor controlled by an external amplifier. The output voltage is adjusted by varying the bias current supplied to the amplifier. The device can also be shut down by setting the shutdown pin (SD) to a low logic level, reducing the device power consumption to less than 0.7uA.

Features

• Low Dropout Voltage (VIN to VOUT- 130 mV)
• Wide Operating Input Voltage Range (0.45V to 5.5V)
• Low Operating Current (< 10uA)
• Max Output Current (800mA)
• Shutdown Pin Feature

Applications

The TPS75333QPWPR is well suited for a variety of low-power applications, such as medical, automotive, home entertainment and industrial equipment. Its small package size and low operating current make it an ideal choice for space-constrained applications. Its wide input voltage range and low dropout voltage make it suitable for applications where power management is important.

The device is also well suited for applications in smart meters, medical devices, sensors and wireless network control cards, where ultra-low power and space saving are critical. The device\'s low operating current, wide input voltage range, high efficiency and shutdown pin make it an ideal power management solution for a range of applications.
