  • TPS7A88-Q1  -  TPS7A88-Q1 is a dual-channel, low-noise, 1-A LDO.

Description

The TPS7A52-Q1 device is a low-noise (4.4 µVRMS), low-dropout linear regulator (LDO) capable of sourcing 2 A with only 115 mV of maximum dropout. The device output voltage is adjustable from 0.8 V to 5.2 V using an external resistor divider.

The combination of low-noise (4.4 µVRMS), high-PSRR, and high output current capability makes the TPS7A52-Q1 ideal to power noise-sensitive components such as those found in radar power and infotainment applications. The high performance of this device limits power-supply-generated phase noise and clock jitter, making this device ideal for powering RF amplifiers, radar sensors, and chipsets. Specifically, RF amplifiers benefit from the high-performance and 5.0-V output capability of the device.

For digital loads [such as application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), and digital signal processors (DSPs)] requiring low-input voltage, low-output (LILO) voltage operation, the exceptional accuracy (1% over load and temperature), remote sensing, excellent transient performance, and soft-start capabilities of the TPS7A52-Q1 provides optimal system performance.

The versatility of the TPS7A52-Q1 makes the device a component of choice for many demanding applications.
