This • Low Noise: 30 µV RMS Typ (10 kHz to 100 kHz) topology is stable using output capacitors with low • 0.5% Initial Accuracy ESR and even allows operation without a capacitor. • 1% Overall Accuracy (Line, Load, and It also provides high reverse blockage (low reverse Temperature) current) and ground pin current that is nearly constant over all values of output current. • Less Than 1 µA Max I Q in Shutdown Mode • Thermal Shutdown and Specified Min/Max The TPS732xx uses an advanced BiCMOS process Current Limit Protection to yield high precision while delivering low dropout voltages and low ground pin current. Current • Available in Multiple Output Voltage Versions consumption, when not enabled, is under 1 µA and – Fixed Outputs of 1.2 V to 5 V ideal for portable applications. The low output noise – Adjustable Outputs from 1.2 V to 5.5 V (30 µV RMS with 0.1 µF CNR) is ideal for powering VCOs. These devices are protected by thermal – Custom Outputs Available shutdown and foldback current limit. (1) Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.
