1-1 Introduction
Introduction
This user’s guide describes the TPS70151EVM–152 low dropout, dual-output
evaluation module (SLVP152). LDOs provide ideal power supplies for rapidly
transitioning DSP loads. The TPS701xx family of devices is designed to
provide a complete power management solution for DSP, processor power,
ASIC, FPGA, and digital applications where dual output voltage regulators are
required. Easy programmability of the sequencing function makes this family
ideal for any DSP applications with power sequencing requirement.
Differentiated features, such as SVS supervisory circuit, manual reset inputs,
and enable function, provide a complete system solution. Moreover, with its
low quiescent current, low dropout voltage, low output noise, high PSRR, fast
transient response, and high accuracy compared to standard LDOs, the
TPS701xx provides an ideal solution where standard linear regulators are too
inefficient or too slow and where a switch converter solution or the source
power supply is too noisy.
