TPS73201QDRBRQ1 Texas Instruments MCU

TPS73201QDRBRQ1 Overview

The TPS732-Q1 family of low-dropout (LDO) voltage regulators uses a new topology: an NMOS pass element in a voltage-follower configuration. This topology is stable using output capacitors with low ESR, and even allows operation without a capacitor. The topology also provides high reverse blockage (low reverse current) and ground pin current that is nearly constant over all values of output current.

The TPS732-Q1 family of devices uses an advanced BiCMOS process to yield high precision while delivering low dropout voltages and low ground pin current. Current consumption, when not enabled, is under 1 μA and ideal for portable applications. The extremely low output noise (30 μV_RMS with 0.1-μF C_NR) is ideal for powering VCOs. These devices are protected by thermal shutdown and foldback current limit.
